sound are longitudinal waves while water waves are transverse waves
sound waves are made by amplitudes
Sound waves are made whenever and wherever there is a sound.
pressure waves
there are none
Light is made up of waves - of a type known as electromagnetic waves.
They do not have natural waves but if someone did a belly flop into the water then waves would be made.
Waves are made in the daytime the same way they are made at nighttime. Primarily by wind, and occasionally by seismic shocks.
no, they are made up of light waves, similar to radio waves and both are in the same spectrum (the electromagnetic spectrum) but they have different wavelenghts.
Beaches are made from material deposited by waves.
Electromagnetic waves.
Diffraction is a typical phenomenon for all sorts of waves. So is interference - another clue that light is made of waves.
