Start by recalling the relationship between frequency and wavelength for electromagnetic radiation, which is given by the equation: , where is the speed of light, is the wavelength, and is the frequency.
The speed of light is a constant, approximately meters per second.
Rearrange the equation to solve for wavelength : .
Substitute the given frequency Hz into the equation, along with the speed of light.
Calculate the wavelength in meters, then convert it to nanometers by multiplying by to get the final answer in nanometers.
