I have read this millions of time on internet that laser spot can move faster than light. but i can't understand how.
For example if we point our laser source towards moon then after 1.2 seconds our laser light reaches the surface of moon and creates a spot there, now if i move my laser source in order to move the spot on surface of moon then after moving my laser source the first photons again take 1.2 seconds to reach the moon so the laser spot on moon can only move after 1.2 seconds to the new location. so there will always be a lag between the previous and new position of the spot.
Now can some one explain me how it is possible to move the laser spot faster than light ?
I would be very thankful.
