Question: A wave travels with a frequency of 500 Hz and a wavelength of 2 m. What is its speed?

Options:

  1. 250 m/s
  2. 1000 m/s
  3. 500 m/s
  4. 200 m/s

Correct Answer: 250 m/s

Solution: 

The speed of the wave is given by v = fλ. Here, v = 500 Hz * 2 m = 1000 m/s.

Questions & Step-by-Step Solutions

A wave travels with a frequency of 500 Hz and a wavelength of 2 m. What is its speed?
  • 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) = 2 m.
  • Step 3: Substitute the values into the formula: v = 500 Hz * 2 m.
  • Step 4: Calculate the speed: v = 1000 m/s.
  • Wave Speed Calculation – The speed of a wave can be calculated using the formula v = fλ, where v is speed, f is frequency, and λ is wavelength.
