Wave formula:

The triangle for the formulas

Example question:

A wave in a pond has a speed of 0.15 m/s and a time period of 2 seconds. Calculate:

a) The frequency of the wave

b) The wavelength of the wave

Answer:

Given:

V = 0.15m/s

T = 2 secs

F = ?

λ = ?

(A) F = 1/t

F = 1/2 hertz

(B) Wavelength = wave speed/frequency
