Question

What is the wavelength of a photon with a frequency of 7.81 x 1014 Hz?

Answer 1

Explanation:

If you know the frequency of the photon, you can calculate the wavelength using the equation λ=cν where c is the speed of light and ν is the frequency.

λ=cν

f=T^-1,f=1/7.81×1014s

c=3×10^8m/s

λ=3×10^8m/s×1/7.81.×1014s

λ=37881.94m
