Question: A wave travels through a medium with a speed of 500 m/s and has a wavelength of 5 m. What is its frequency? (2021)

Options:

  1. 100 Hz
  2. 50 Hz
  3. 200 Hz
  4. 250 Hz

Correct Answer: 100 Hz

Exam Year: 2021

Solution: 

Frequency (f) = speed (v) / wavelength (λ) = 500 m/s / 5 m = 100 Hz.

Questions & Step-by-Step Solutions

A wave travels through a medium with a speed of 500 m/s and has a wavelength of 5 m. What is its frequency? (2021)
  • Step 1: Identify the speed of the wave, which is given as 500 m/s.
  • Step 2: Identify the wavelength of the wave, which is given as 5 m.
  • Step 3: Use the formula for frequency, which is Frequency (f) = speed (v) / wavelength (λ).
  • Step 4: Substitute the values into the formula: f = 500 m/s / 5 m.
  • Step 5: Calculate the frequency: 500 divided by 5 equals 100.
  • Step 6: Conclude that the frequency of the wave is 100 Hz.
