Question: A wave has a frequency of 500 Hz and a wavelength of 0.68 m. What is the speed of the wave? (2021)

Options:

  1. 340 m/s
  2. 500 m/s
  3. 680 m/s
  4. 250 m/s

Correct Answer: 340 m/s

Exam Year: 2021

Solution: 

The speed of the wave can be calculated using the formula v = fλ. Thus, v = 500 Hz * 0.68 m = 340 m/s.

Questions & Step-by-Step Solutions

A wave has a frequency of 500 Hz and a wavelength of 0.68 m. What is the speed of the wave? (2021)
  • Step 1: Identify the formula for wave speed, which is v = fλ, where v is speed, f is frequency, and λ is wavelength.
  • Step 2: Write down the given values: frequency (f) = 500 Hz and wavelength (λ) = 0.68 m.
  • Step 3: Substitute the values into the formula: v = 500 Hz * 0.68 m.
  • Step 4: Calculate the result: 500 * 0.68 = 340 m/s.
  • Step 5: Conclude that the speed of the wave is 340 m/s.
  • Wave Speed Calculation – The speed of a wave can be calculated using the formula v = fλ, where v is the speed, f is the frequency, and λ is the wavelength.
