Difference between Tides and Waves. Key Difference: Tides are the rise and fall of sea level that is caused by the gravitational pull of the moon and the sun on the Earth. Waves are actually energy that moves across the surface of the water.
Rather, we are talking about the waves that transmit radio signals. The main difference between radio waves and sound waves is that radio waves are a type of electromagnetic wave that can travel when there is no medium, whereas sound waves are a type of mechanical wave that cannot travel if there is no medium. What are Radio Waves. Radio waves are electromagnetic waves. These are waves composed of electric and magnetic fields, which are oscillating at right angles to each other. The energy of an electromagnetic wave propagates at a direction at right angles to the oscillations in both the electric and magnetic fields.
