We need to use:
Speed of light = frequency x wavelength
hence
Frequency = speed of light / wavelength
And
Wavelength = speed of light / frequency
Explanation:
The speed of light is
So question (a) is
This in the ultraviolet part of the spectrum
And for (b)
This is in the microwave part of the spectrum
For (c) we can work out distance by multiplying speed by time taken
