Question

What is the frequency of a wave that has a speed of 240 m/s and a wavelength of 0.20 m?

Answer 1

• Frequency of the wave = 1200 Hertz

Step-by-step explanation:

Given :-

• Wavelength = 0.20 m
• Wave speed = 240 m/s

Solution :-

Frequency of a wave is given by :

• 
  `\sf F = (v)/(\lambda)`

where,

• F is frequency,
• v is wavespeed ,
• 
  `\sf\lambda` is wavelength

On substituting the values we get :

`\dashrightarrow \sf F = (240)/(0.20) \\ \\ \dashrightarrow \rm F = 1200 \: Hz \\`

• Hence, Frequency of the wave is 1200 Hertz
