A 25.0-pm x-ray photon scatters off a free electron at A
(Fig. P27.26), producing a photon of wavelength A' traveling at
an angle 0 = 40.0° relative to the first photon's direction. This
second photon scatters off another free electron at B, produc-
ing a photon with wavelength A" and moving in a direction
directly opposite the first photon. Determine the wavelengths
(a) A' and (b) A".

Figure P27.26
A hydrogen atom on the surface of the sun radiates a photon with wavelength 1800 nm.
The sun has a radius, Tsun = 6.96 × 108 m, and a mass, Msun = 1.99 × 10³⁰ kg.
(a) Calculate the change in wavelength when the photon is observed a long way -
effectively at an infinite distance from the sun (or any other massive object).
(b) How fast and in what direction would the observer have to move in order to cancel
this change in wavelength?
Ex1/ A photon with momentum p = 1.02 MeV/c is scattered by a stationary free
electron. Its momentum on scattering becomes p' = 0.255 MeV/c. At what angle
is the photon scattered?
Ex2/ A photon is scattered at an angle =120° by a stationary free electron. As a
result the electron acquires a kinetic energy
of the incident photon.
T = 0.45 MeV. Find the energy
