Calculating Wavelength without distance

  1. Jul 29, 2005 #1
    A question has been given to me: what is the wavelength for light with a frequency of 5.58×1014 Hz? How do you find the wavelength without the distance?

    You can use the equation [itex]c = f\lambda[/itex], where c is the speed of light (in free space).

    That formula includes the wavelength which is what I am trying to solve for. I am a first year physics student so you'll have to take it easy.

    Well if it didn't include the wavelength you couldn't solve for it, could you?

    c= λf so λ= c/f.

    You are given the frequency, f, and you know, or can look up, the speed of light, c.
