A drop of water falls into a puddle consistently every 0.6 seconds. This creates waves along the surface of the wave with 0.04 m distance from crest to trough. Sometime later you measure the distance from crest to trough to be 0.07 m. How did the frequency of the dipping water change?
A wave is created along a string by a wave generator set to 50 Hz. You measure the distance from crest to crest to be 0.2 m. What is the speed of the wave?How does the wave speed and wavelength change if you set the generator of 150 Hz?
