We are being asked to calculate the wavelength of a photon with a frequency equal to 3.26x1015 Hertz.
Wavelength, frequency, and the speed of light are connected by the following equation:
c = speed of light, m/s
λ = wavelength, in m
ν = frequency, Hz (Hertz)
We can rearrange the equation to isolate the wavelength (λ):
