Question

A wave travels through water at a speed of 3 m/s and has a frequency of 10 Hz. What is the wavelength of the wave?

Answer 1

V=wavelength*frequency

3 m/s=wavelength*10 Hz

3m/s=10 Hz

wavelength= .3

Answer 2

Answer:

Wavelength of the wave, λ = 0.3 m

Explanation:

It is given that,

The speed of the wave, v = 3 m/s

The frequency of the wave, f = 10 Hz

We know the relationship between the frequency, wavelength and the speed of the wave. Mathematically, it can be written as :

$speed=frequency\times lambda$

or

$v=f\times \lambda$

$\lambda=\dfrac{v}{f}$

$\lambda=\dfrac{3\ m/s}{10\ Hz}$

$\lambda=0.3\ m$

Hence, the wavelength of the wave is 0.3 m
