Lucky for us, the average salaries of UK jobs are revealed annually by those helpful number-crunching pixies at the Office of National Statistics. The survey of a whopping 21,563,000 people's earnings will either delight or depress you depending on what end of the scale you see yourself in the next five years.
This is what is called transverse and longitudinal waves. The difference between transverse and longitudinal waves is the direction in which the waves shake. If the wave shakes perpendicular to the movement direction, it's a transverse wave, if it shakes in the movement direction, then it's a longitudinal wave. [Transverse Wave] It is easy to imagine a transverse wave. The waves of the ocean and the waves transmitted from a tightened rope when shaken are transverse waves.
Waves are a wiggle in space cause by a vibration or disturbance. They have the ability to carry energy from one location to another. There are two different types of waves; transverse and longitudinal. A transverse wave is when the wave is vibrating perpendicular to the direction the wave is traveling. A longitudinal wave, also called a compression wave, is a wave in which the vibration is in the same direction as that in which the wave is traveling. How frequently a wave or vibration occurs during a span of time, determines the waves frequency. Frequency is the number of waves per unit time.
