Physics, asked by dhruvasakhare, 1 year ago

if we are going at the speed of light,what speed will we measure of a light beam going parallel to us?

Answered by predators

we will measure light speed for 1 metre. because we set it as base
and speed of light is 0m/s because it remains constant with respect to us

dhruvasakhare: can you explain it a bit more

Answered by alex57

suppose if are going at the speed of light the relative speed of light beam which is parallel to us will be zero.
As we are moving at the same speed and at the same direction.
But suppose a light beam is moving antiparallel to us it means it is parallel but opposite in direction then in this case the relative speed of light beam will be double of actual speed of light.

THANK YOI

dhruvasakhare: but the speed of light is constant no matter the position of the observer

alex57: yes the speed of light is constant but for the observer who is standing on the surface of earth

alex57: for those who are moving observe less speed but change will be very less with respect to the speed of light

dhruvasakhare: 2nd Postulate of Relativity. The speed of light in a vacuum is the same for all observers, regardless of their motion relative to the source

alex57: if we are the source of light then only for us the speed of that light beam will be constant which is equal to the actual speed of light
