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?
Solar radiation falls on Earth's surface at a
rate of 1900 W/m².
Assuming that the radiation has an average
wavelength of 580 nm, how many photons per
square meter per second fall on the surfaces?
The speed of light is 3 × 10° m/s and Planck's
constant is 6.62607 × 10-34 J. s.
Answer in units of photon/m² · s.
