Problem: What is the frequency of light for which the wavelength is 7.1x102 nm?a. 4.2x105 s-1a. 4.2x1014 s-1a. 2.4x10-6 s-1a. 2.1x102 s-1

Wavelength, frequency, and the speed of light are connected by the following equation:

$c = λν$

c = speed of light, m/s
λ = wavelength, in m
ν = frequency, Hz (Hertz)
