Question

Light is massless still it is has momentum???

Answer 1

HEY MATE ✌️✌️

Here's your answer,

According to theory, light has energy and momentum but no mass, and this is confirmed by experiment to within strict limits. Even before it was known that light is composed of photons, it was known that light carries momentum and will exert pressure on a surface. This is not evidence that it has mass since momentum can exist without mass.

HOPE that helps..

Answer 2

Answer:

Explanation:

Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum. ... If a particle has no mass (m = 0) and is at rest (p = 0), then the total energy is zero (E = 0). But an object with zero energy and zero mass is nothing at all.
