Standing waves in water are produced most often by periodic water waves. True or False

True

Explanation:

Standing waves are also known as stationary waves. Standing waves move back and forth in time.

Standing waves occur due to a long and deep sound vibration also known as resonance. They are produced by waves that possess similar frequency, amplitude and wavelength that is moving in an opposite direction to the wave.

True

Explanation:

Standing waves are usually static or stationary i.e they are stagnant.

Standing waves in water are produced most often by periodic water waves which are made to be reflected from a barrier. A periodic wave is a waveform that transfers energy.

the acceleration due to gravity is 10ms-1

displacement=time*velocity

d=3*30=90ms-1
