Reflector Light Disc
May 23rd, 2009
What causes a slight recoil in the reflector disc of searchlight when light beam is switched on?
Ref.question asked seeking clarification of a doubt that wheather the light beam contains any particles of impercepible mass which collectively exerted a recoiling pressure on the concave reflector satisfying the third law of motion and yet could attain the ultimate velocity as verified experimentally without contradicting Theory of Relativity.
Light exerts a very small amount of pressure.
Camera artifacts of the type found in STS-75 tether footage.
