What two factors determine wave speed? Why does the speed of a wave on the surface of water differ from the speed of a sound wave in water

Answer 41

Wave length and frequency. Because sound travels faster in water than air

Question 42

Describe the two kinds of mechanical waves.

Answer 42

When the vibration is at right angles to the direction of travel the wave is a transverse wave. I'd the vibration is parallel to the direction of wave movement it is a longitudinal wave.
