Question: If the speed of a wave in a medium is 300 m/s and its wavelength is 3 m, what is the frequency of the wave?

Options:

  1. 100 Hz
  2. 150 Hz
  3. 200 Hz
  4. 300 Hz

Correct Answer: 150 Hz

Solution: 

Frequency f = v/λ = 300 m/s / 3 m = 100 Hz.

Questions & Step-by-Step Solutions

If the speed of a wave in a medium is 300 m/s and its wavelength is 3 m, what is the frequency of the wave?
  • Step 1: Identify the speed of the wave (v). In this case, v = 300 m/s.
  • Step 2: Identify the wavelength (λ). In this case, λ = 3 m.
  • Step 3: Use the formula for frequency (f), which is f = v / λ.
  • Step 4: Substitute the values into the formula: f = 300 m/s / 3 m.
  • Step 5: Calculate the frequency: f = 100 Hz.
  • Wave Speed, Wavelength, and Frequency – The relationship between wave speed (v), wavelength (λ), and frequency (f) is given by the formula f = v/λ.
