Question

How do you know nothing travels faster than light? Give an example to justify

Answer 1

Answer:

the speed of light is as hai 80 lakh kilometre per second.light, 10, propagates nearly a million times faster than anything else. hence, when lightning and thunder occur together the flash of light reaches us in practically zero time. the sound of the thunder however takes few seconds to reach us. we, therefore, hear the thunder a little later after seeing the flash off the light.
