Question

What is the frequency of a wave that has a wavelength of 4 meters and a speed of 40 m/s? 36 hz 44 hz 10 hz 160 hz?

Answer 1

Velocity = frequency * wavelength
40/4 = 10
Your answer is 10 Hz.

Answer 2

Answer: The frequency the wave is 10 Hz

Step-by-step explanation:

Wave speed is defined as the product of its wavelength and frequency.

Mathematically,

`\text{Wave speed}=\lambda* \\u`

where,

Wave speed = 40 m/s

`\lambda` = wavelength of the wave = 4 m

`\\u` = frequency of the wave = ?

Putting values in above equation, we get:

`40m/s=4m* \\u\\\\\\u=(40m/s)/(4m)=10s^(-1)=10Hz`

Hence, the frequency of the wave is 10 Hz
