Question

A string is being driven by a motor with a frequency of 10 Hz. If the speed of the waves travelling down the string is equal to 24 m/s, what is the wavelength?

Answer 1

Answer:

λ = 2.4 m

Explanation:

The speed of a wave is defined as the product of the frequency and the wavelength of that wave:

$v = f\lambda$

where,

v = speed of wave = 24 m/s

f = frequency of wave = 10 Hz

λ = wavelength of the wave = ?

Therefore,

$24\ m/s = (10\ Hz)\lambda\\\\\lambda = \frac{24\ m/s}{10\ Hz}$

λ = 2.4 m
