What is the frequency of light with a wavelength of 7.9 x 10^-9 m? ( the speed of light is 3.00 x 10^8)

A.) 3.80 x 10^16
B.) 2.37 Hz
C.) 2.37 m
D.) 3.80 x 10^16 Hz

Respuesta :

using the formula v=f times lambada
then v=the speed of light.
and f=what’s we’re looking for
and lambada=the wavelength.

so then you sub what you have (v and lambada) in the formula.
then multiply the frequency(f) by the given wavelength and then solve for f
