What is the frequency of red light with a wavelength of 645 nm?
marin [14]

Answer:

4.64E14

Explanation:

First convert 645 nm to m = 6.4500E-7m. The equation for finding v with these values is the speed of light/wavelength. so 2.998E8/6.4500E-7m.

so your v or frequency would equal 4.64E14

Fun fact you know this is visible light because the visible light range is within the E14 range.
