4. A laser wavelength 500nm and intensity 5.0 KW m2 produces a vibration in an atom on 5 x 10-10 m. a) Label and include values for the graph below of displacement and time for the vibrations by Determining the frequency . Working out the period AAAA (4 marks) b) On the same diagram repeat sketch what the wave would look like if the wavelength was 1.00um and the intensity was 2.50 kWm-2
