Solution: Calculate the wavelength of a red light photon in nanometers if the frequency is 4.6 × 1014 Hz?

Problem

Calculate the wavelength of a red light photon in nanometers if the frequency is 4.6 × 1014 Hz?

Solution

We are being asked to determine the wavelength of a red light photon at 4.6x1014 Hz. Wavelength, frequency, and the speed of lightare related by the following equation:

c = λ·v

c = speed of light = 3.0x108 m/s
λ = wavelength, in m
ν = frequency, s-1 or Hz

Calculate the wavelength (λ):
