Answer to Question #276224 in Physics for Kaidi

Question

1. What is the frequency of a wave, given that its period is about 6.7s?

2. If a water wave oscillates up and down 7 times each second and the distance between wave crests is 2.7m, what is its wavelength?

Answer 1

1. The frequency is

$f=1/T=1/6.7=0.149\text{ Hz}.$

2. The wavelength is the distance between two successive crests: 2.7 m.
