Gamma rays are photons with very high energy. How many light with a of 500 nm would you need to match the energy of a gamma ray photon with energy 4.1 x 10-13 J a) 1.4 x 108 b) 6.2 x 109 c) None of the other answers d) 3.9 x 103 e) 1.0 x 106 A laser produces a beam of 4000nm light A shutter allows a pulse of light, 30 ps in duration, to pass. Which of the following is closest to the uncertainty in the energy of a photon in the pulse? a) 10-4 ev b) 10-6 eV c) 10 2 eV d) 10-3 eV e) 10 5 eV
