1. Speed Formula - Waves

2. To find wave speed Formula
V = λ x f Speed (velocity) = Wavelength x frequency
Sample Problem 1:
Find the speed of a wave with a wavelength of 3m and a frequency of 10 Hz
V = 3m x 10 Hz
V = 30 m/s

3. To find wavelength Formula λ = v f Sample Problem:
Find the wavelength of a wave that is traveling at 100 m/s with a frequency of 3 Hz.
λ= 100m/s λ= 33.33m
3 Hz

4. To find frequency Formula f = v λ
Find the frequency of a wave that is traveling at 345 m/s with a wavelength of .25m
f = 345 m/s f= Hz
.25m
