4) Consider the Compton effect, write down the formula giving the difference of the wavelengths for scattered and incident light in terms of the scattering angle of the photon and the Compton wavelength. a) What is the difference in the wavelengths if the scattered photon is perpendicular to the incident one? b) Calculate the absolute maximum and minimum of the difference in the wavelengths. (Hint: take the derivative of the r.h.s. w.r.t. the angle and set it equal to zero) c) In all 3 cases find the angle the scattered electron makes with respect to the horizontal.
1) The Sun cranks out about 4 x 1026 J/s, i.e. its radiant power pe = 4 x 10²6 W. For a square meter of area here on the Earth whose surface normal points directly to the Sun, how many watts are received? How many 550-nm photons would that correspond to? (The Earth-Sun distance is about 150x100 km.)
