The photo has been taken through a diffraction grating.
B and C are street lights and A is a flood light.
Looking at the spectra B and C are similar. What is the difference in the spectra produced by the two types of light?
I don’t get the question of ” What is the difference in the spectra produced by the two types of light?”
They both have the same colours, how are they different?
