1. Calculate the maximum ¢l/l of Compton scattering for blue light (l = 480 nm). Could this be easily
2. What wavelength photons are needed to produce 30.0-keV electrons in Compton scattering?
3. A typical person can detect light with a minimum intensity of 4.0 X 10-11 W/m2. For light of this intensity and A = 550 nm, how many photons enter the eye each second if the pupil is open wide with a diameter of 9.0 mm?
4. A copper wire carrying a high current glows "red hot" just before the wire melts at a temperature of 1085°C.
(a) What is the peak wavelength of the emitted radiation?
(b) Given your answer to part (a), how can the wire be "red hot"?
