Refraction of light and wavelength

  • #1
Light of wavelength 680 nm in air enters water making an angle of 40 degrees with the normal. Find the angle of refraction and the wavelength of light in water.

I found the angle of refraction, but I don't know how to calculate the wavelength with this information.
