Post by: Brelou on Feb 26, 2017 A certain photon after being scattered from a free electron at rest moves at an angle of 120° with respect to the incident direction. If the wavelength of the incident photon is 0.611 nm, what is the kinetic energy of the recoiling electron?
A) 1.5 × 10-18 J B) 2.1 × 10-18 J C) 3.1 × 10-18 J D) 4.3 × 10-18 J E) 5.2 × 10-18 J Title: Re: A certain photon after being scattered from a free electron at rest moves at an angle of 120° ... Post by: longhair on Feb 26, 2017 Content hidden
