Asked in ETEA MDCAT 2008 2008Moderate

The wavelength of a wave traveling with.speed v·and having frequency f is:

Correct answer: A. λ = v/f

  • A. λ = v/f
  • B. λ = vf
  • C. λ = f/v
  • D. None of above

Explanation

speed = frequency x wavelength Rearrange the formula and you get: wavelength = speed / frequency

About Wave Speed

Wave speed is the rate at which a disturbance or wave pattern travels through a medium, given by v = fλ, where f is frequency and λ is wavelength. Questions examine how speed changes between media, the relation among frequency, wavelength and period, and why wave speed is not the same as particle vibration speed.
