The momentum of light is exactly reversed when reflected straight back from a mirror, assuming negligible recoil of the mirror. thus the change in momentum is twice the photon momentum. suppose light of intensity 1.00 ~\text{kw/m}^21.00 kw/m 2 reflects from a mirror of area 2.00 ~\text{m}^22.00 m 2 . using the most general form of newton’s second law, what is the force on the mirror?
