Light has no mass.

Explanation:

Light is electromagnetic radiation comprised of photons. Photons have no mass (please see the reference for photon ). The energy of a photon is described by the equation:

#E=hf#

Where #h# is Planck's constant and #f# is the frequency of the wave in which the photon is contained.
