Questions & Step-by-Step Solutions

If a wave has a speed of 300 m/s and a frequency of 150 Hz, what is its wavelength? (2023)
  • Step 1: Understand the wave equation, which is v = fλ, where v is the speed of the wave, f is the frequency, and λ (lambda) is the wavelength.
  • Step 2: Rearrange the equation to solve for wavelength (λ). This gives us λ = v / f.
  • Step 3: Plug in the values: speed (v) is 300 m/s and frequency (f) is 150 Hz.
  • Step 4: Calculate the wavelength: λ = 300 m/s / 150 Hz.
  • Step 5: Perform the division: 300 divided by 150 equals 2.
  • Step 6: Conclude that the wavelength (λ) is 2 meters.
  • Wave Equation – The relationship between wave speed (v), frequency (f), and wavelength (λ) is given by the equation v = fλ.
