The Speed of Sound Factors Affecting Wave Speed. The speed of any wave depends upon the properties of the medium through which the wave is traveling. Typically there are two essential types of properties that affect wave speed - inertial properties and elastic properties.

Oceanography: waves Waves travel effortlessly along the water's surface. This is made possible by small movements of the water molecules. This chapter looks at how the motion is brought about and how waves can change speed, frequency and depth. waves and wind. The wind blows over the water, changing its surface into ripples and waves. As waves grow in height, the wind pushes them along faster and higher.

Currents, Waves, and Tides: The Ocean in Motion A wave's size depends on wind speed, wind duration, and the area over which the wind is blowing (the fetch). This variability leads to waves of all shapes and sizes. The smallest categories of waves are ripples, growing less than one foot (.3 m) high.

Tag Archives: Index of Refraction Answer: Speed changes, frequency remains constant, and wavelength changes. The front of a wave has some actual width, therefore if the wave does not impinge upon the boundary between media at a right angle, not all of the wave enters the new medium and changes speed at the same time. This causes the wave to bend as it enters a new medium in a process known as refraction.

As the frequency of a wave increases what decreases? The wavelength of waves travelling with the same speed would  decrease if the frequency of the waves increases. This is because,  speed of a wave is the product of the dista … nce of the wavelength  times the frequency of the wave.

Does amplitude affect velocity of a wave? Rating Newest Oldest. Best Answer: It depends on the type of wave. If it is an electromagnetic wave (i.e., light), then the amplitude has absolutely no effect on the velocity. If it is a sound wave traveling through the air, the speed of the wave is always the speed of sound in air (at that particular temperature). However, if it is a wave traveling in water, then the amplitude CAN affect the velocity. Water waves are strange and nonlinear, and the principle of superposition does not apply.

- Important Notes. 1  Velocity depends on the density and elasticity of the transmitting material. 2  Pressure increases within the Earth-therefore density increases. 3  P-waves travel in all mediums. 4  S-waves travel only in solids. 5  P-waves travel faster than S-waves.

NOAA's National Weather Service Tsunami wave speed is controlled by water depth. Where the ocean is over 6,000 meters (3.7 miles) deep, unnoticed tsunami waves can travel at the speed of a commercial jet plane, over 800 km per hour (500 miles per hour). Tsunamis travel much slower in shallower coastal waters where their wave heights begin to increase dramatically.

LSA Weight Limits: Is Higher Better? When a wave goes from deep water to shallow water, it decreases in size and strength. This is because shallow water does not have the required power to transmit the wave, and … so its velocity decreases.ertainly shallow water will travel faster than deep water for the same volume of water moving past a point p … er unit of time. And if you think about it, it will become clear. Let's look at water in a pipe and make a comparison.   Two pipes of different diameter have water moving through them.

- Return to Coastal Currents: Waves. The highest surface part of a wave is called the crest, and the lowest part is the trough. The vertical distance between the crest and the trough is the wave height. The horizontal distance between two adjacent crests or troughs is known as the wavelength. Wave height is affected by wind speed, wind duration, or how long the wind blows, and fetch, which is the distance over water that the wind blows in a single direction. If wind speed is slow, only small waves result.

Speed of sound If the wave is traveling in a dispersive medium, the frequency of the wave will affect the speed (and the group delay and phase delay will not be the same). The type of dispersive medium also determines whether high frequency waves will travel faster or slower than lower frequency waves.he wavelength of any sound wave will be proportional to its speed and inversely proportional to its frequency. l = c / f, where l is the wavelength, c is the speed, and f … is the frequency. In air, at sea level, 20 C and dry conditions, the speed of sound is about 340 m/s.

Ask Tom why: How does snow affect the way sound travels? —Luis Rios. Dear Luis, There are multiple explanations. It's easy to understand that, during a snowstorm, falling snow greatly diminishes the distance that sound waves will carry (heavy falling rain has a similar effect). Snow cover also affects the audible distance of sounds. Colorado State Climatologist Nolan Doesken says: When the ground has a thick layer of fresh, fluffy snow, sound waves are readily absorbed at the surface of the snow. However, the snow surface can become smooth and hard as it ages or if there have been strong winds.

- There are three factors that make up waves: 1  Wind speed Length of time the wind has blown. 2  Distance of open water that the wind blows over; called fetch.

Wave period The wave speed, C, can be calculated by dividing the wavelength by the wave period (C=L/T) since a wave travels one wave length each wave period. Waves are classified as deep water waves when the water depth is greater than half the wavelength and, for deep water waves, speed is determined by the wavelength.his is because waves with the longest wavelengths and wave period travel faster in deep water. Therefore as a swell approaches land from a long distance the waves with the longest wavelengths and highest period will arrive first. The local winds will then decide the surface quality that goes with it.

Energy, Plants & Man Thus amplitude and frequency are the two factors that affect the energy transferred by a wave: the height of the wave, and the number of waves passed by each second. Energy Loss In physics, we say that energy cannot be created or destroyed, it can only move from one place to another.

Sound The behavior of sound propagation is generally affected by three things: 1  A relationship between density and pressure. 2  The propagation is also affected by the motion of the medium itself. 3  The viscosity of the medium also affects the motion of sound waves.

Refraction of Sound Waves The speed of a sound wave in air depends on the temperature (c=331 + 0.6 T) where T is the temperature in oC. Often the change in the wave speed, and the resulting refraction, is due to a change in the local temperature of the air.

Wave Speed The speed of the wave is not affect by its wavelength and its frequency. Rather the speed of wave is not affected by the characteristics of the wave but by the characteristics of the medium in which it is traveling.S_{W}$= speed of the wave. $D_{W}$ = distance travelled by crest or trough of the wave. T = time taken to travel the distance $D_{W}$. This equation is the speed of any particle according to the classical theory of physics and it is equally applicable to the waves due to their dual nature.

The Speed of Sound The faster a sound wave travels, the more distance it will cover in the same period of time. If a sound wave were observed to travel a distance of 700 meters in 2 seconds, then the speed of the wave would be 350 m/s. A slower wave would cover less distance - perhaps 660 meters - in the same time period of 2 seconds and thus have a speed of 330 m/s. Faster waves cover more distance in the same period of time.

Properties of Seawater Sound travels faster through liquids than it does through air. Temperature, salinity, and density all affect the speed at which sound travels in seawater. The velocity of sound through seawater therefore varies with depth.

Frequency of a wave remaining constant through changes in medium As you go from one medium to another, the frequency stays the same, but the wavelength changes. The speed of the wave traveling from one medium to another changes, and that change is proportional to the change in wavelength. As you go from one medium to another, the refractive index, n, for that medium changes.

Wind Factors The amount of deflection depends on the size of the lake, with a max of about 45 degrees occurring on the high seas and massive inland waters. Deflection also increases with wind speed up to about 14 to 18 mph. Wave action often attracts baitfish and triggers bass, walleyes, and other gamefish to feed in shallow water.

Wind wave The speed of all ocean waves is controlled by gravity, wavelength, and water depth. Most characteristics of ocean waves depend on the relationship between their wavelength and water depth. Wavelength determines the size of the orbits of water molecules within a wave, but water depth determines the shape of the orbits.
