Wave speed

• What is the equation for wave speed?

  wave speed = frequency x wavelength
• What happens to waves that are transmitted from one medium to another?

  The wave speed and wavelength changes
• What is the speed of a wave?

  The speed at which the wave moves (Or at which energy is transferred)
• During the direct observation of ripples of on the surface of water, why is it important that the waves are slow enough?

  This allows you to measure their speed with a stopwatch
• True or False : As waves are transmitted from one medium to another, their frequency changes

  False
• All waves obey the wave equation. What does this mean about speed and wavelength?

  Speed and wavelength are directly proportional : doubling the speed doubles the wavelength
