(5) The total power output from a star is 4.5 x 1026 W. Assuming that all the emitted radiation has a wavelength λ = 550 nm, calculate the number of photons that are emitted per second.
(3) A spectrometer used in a measurement of the Compton effect has a spectral resolution of Aλ/2 = 0.5%. Find the wavelength of the incident photons that would be required in order to resolve (a) Scattered photons at an angle of 38° (b) Scattered photons at an angle of 90° (c) Comparing parts (a) and (b), which measurement is easier, keeping in mind that it is harder to make higher energy photons? What factor can you think of that might make the measurement at 0= 90° harder than the measurement at 0= 38°?
(i) Monochromatic light of frequency 6.0 × 1014 Hz is produced by a laser. The power emitted is 2.0 × 10-3 W. Estimate the number of photons emitted per second on an average by the source. (ii) Draw a plot showing the variation of photoelectric current versus the intensity of incident radiation on a given photosensitive surface.
