A 1ns laser pulse from a neodymium-YAG laser at 532 nm, comprise 5J.
i) Evaluate the energy and momentum of all photon.
ii) Find out the number of photons in the 1ns pulse of light?
iii) When all of the photons are fully absorbed by an object, determine the force applied on the object by laser light?
iv) When the light then passes via a frequency doubler; compare this new force to the prior force.
