Light has mass since it has energy.

Energy depends on the wavelength/frequency.

Einstein and Planck get credit for working this out.

Using red light of wavelength 650nm travelling in a vacuum we get a mass of 3.4x10^-36 kg. The weight depends on the gravity, but on Earth that would weigh roughly 3.332x10-35 N.

A ray of light weighs nothing because light has no mass. Weight is a measurement of the force of gravity acting on an object's mass, and since light has no mass, it does not have weight.
