In the Compton effect, a photon of wavelength 
and frequency f is scattered from an electron. Initially, at rest
A. the electron gains energy from the photon so that the scattered photon's wave length is less than
B. the electron gives energy to the scattered photon so the photon's frequency is greater than f.
C. momentum is not conserved, but energy is conserved.
D. the photon loses energy so that the scattered photon has a frequency less than f.

Thermal Expansion: An aluminum rod is 10.0 cm long and a steel rod is 80.0 cm long when both rods are at a temperature of 15°C. Both rods have the same diameter. The rods are now joined end-to-end to form a rod 90.0 cm long. If the temperature is now raised from 15°C to 90°C, what is the increase in the length of the joined rod? The coefficient of linear expansion of aluminum is 2.4 × 10-5 K-1 and that of steel is 1.2 × 10-5 K-1.
