We are being asked to calculate the wavelength of a radiation with a frequency equal to 5.17x1014 s-1.


Wavelength, frequency, and the speed of light are connected by the following equation:

c=λν

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


We can rearrange the equation to isolate the wavelength (λ):
