Suppose, you have light of frequency 1000mm (f = 1000mm). It is known that E (energy) = h (plank's constant ) * f (frequency of light) or E = 6.62607004e-34 * 1000 = 6.62607004e-31.
We also know that E = MC^2 or M = E/C^2 which means M = 6.62607004e-31/299792458 * 299792458 => m = 7.3724972e-48 .
So, why do people say light have no mass?
