# equation quiz - wave speed

```Equation Quiz A - Chapter 17
Name: _________________________ Date: _________________ Section: _______
WS = f λ
1.
t=1/f
Sound waves travel at a speed of approximately 345 m/s in air. What is the
frequency of a sound wave that has a wavelength of 0.017 m?
2. Assuming the speed of sound has not changed, what is the wavelength of a sound
wave that has a frequency of 190 Hz?
3. You are at the beach watching the waves roll in. You time them and determine
that they hit the beach every 9 seconds. If the distance between crests is 12 m,
what is the speed of these waves?
