Determine the frequency of light with a wavelength of 3.835 * 10-7 cm. answer in units of hz.

First convert the wavelength to meters:

λ = 3.835 * 10^-7 cm is 0.003835 in meters

The speed of light is:

C = 3.0 * 10^8 m/s

Frequency is the speed the wavelength:

f = C/λ where c is speed of light and λ is the length of the wave

f = 3 * 10^8 m/s / 0.003835 m

f = 7.8227 * 10^10 Hz
