Question

If E= mc²,
does that mean light has mass? Because light is made of light photons and light photons are made of energy and E stands for energy.
So does-
Energy = MASS×c

Answer 1

Answer:

it do not mean the photons ( light) have mass instead

if any object of mass m is travelling with speed of light

(c) , then the objects mass will be converted to energy ,

for finding this energy we use the above mentioned

equation i e E= mc^2
