Problem

A laser pointer used in a lecture hall emits light at 650 nm.

What is the frequency of this radiation?

Solution

To convert between wavelength (λ) & frequency (ν) we use the equation c = ν  λ, where c equals the speed of light ( 3.00 x 10m/s).

Since we are starting with a wavelength and converting it to the frequency we rearrange the equation to:
