Answered by rohit50003

Explanation:

Light is composed of photons, which have no mass, so therefore light has no mass and can't weigh anything. Not so fast. ... But because of Einstein's theory (and the fact that lightbehaves like it has mass, in that it's subject to gravity), we can say that mass and energy exist together.
