Question

what is time of light? obtain its expansion

Answer 1

Einstein's theory of special relativity sets of the speed of light, 186,000 miles per second (300 million meters per second). ... If you could travel at the speed of light, you could go around the Earth 7.5 times in one second. Early scientists, unable to perceive light's motion, thought it must travel instantaneously.

Answer 2

Theory of relativity says that if a spaceship approaches to the speed oflight then the time inside the spaceship will flow slower. If the spaceship travels at the speed of light, then the time inside of the spaceship will stop all together. ... the mass of the body also increases.this is the effect of relativity .
