Consider light fron a laser at a wavelength of 800 nrn, and which outputs pulses of length 8 μιη in their direction of travel. Each pulse has an energy of 50 nJ (a) Sketch the clectric field of the pulse as a function of position at a fixed time. Ensure you label the important length scales. (b) Calculate the number of photons contained in a single pulsc (c) Using the Heisenberg uncertainty principle, estimate the uncertainty in the wavelength of...
Problem 3 Part A The energy levels of atomic mattinium are given by the expression -10.2 eV En = ηλ/2 (a) Draw an energy level diagram showing the lowest four energy levels of atomic mattinium, as well as the ionisation limit. Label each of the energy levels with their quantum number and their energy in electron volts. (b) One of the puzzles of classical physics was that the absorption and emission spectra of atomic gases were different from one another....
