Question: A sound wave travels through air at a speed of 340 m/s. If the wavelength is 0.85 m, what is the frequency of the sound wave? (2022)

Options:

  1. 400 Hz
  2. 300 Hz
  3. 250 Hz
  4. 500 Hz

Correct Answer: 400 Hz

Exam Year: 2022

Solution: 

The frequency f can be calculated using the formula v = fλ. Rearranging gives f = v/λ = 340 m/s / 0.85 m ≈ 400 Hz.

Questions & Step-by-Step Solutions

A sound wave travels through air at a speed of 340 m/s. If the wavelength is 0.85 m, what is the frequency of the sound wave? (2022)
  • Step 1: Identify the speed of the sound wave, which is given as 340 m/s.
  • Step 2: Identify the wavelength of the sound wave, which is given as 0.85 m.
  • Step 3: Use the formula for wave speed, which is v = fλ, where v is speed, f is frequency, and λ is wavelength.
  • Step 4: Rearrange the formula to solve for frequency (f): f = v / λ.
  • Step 5: Substitute the values into the formula: f = 340 m/s / 0.85 m.
  • Step 6: Calculate the frequency: f ≈ 400 Hz.
