Question 4 • Physics

Which equations represent the relationship between wavelength and frequency for a sound wave? Choose three correct answers.

Answer
A
f is equal to lambda over v
B
lambda is equal to f over v
C
lambda is equal to v f
D
v is equal to lambda f
E
f is equal to lambda v
F
lambda is equal to v over f
G
f is equal to v over lambda

Explanation

A wave’s speed, wavelength, and frequency are related by v = λf. Rearranging gives λ = v/f and f = v/λ. Therefore, the correct equations are “v is equal to lambda f,” “lambda is equal to v over f,” and “f is equal to v over lambda.”
