- S1 and S2 in the figure below are effective point sources of radiation, excited by the same oscillator. They are coherent and in phase with eachother. Placed a distance d=4.17m apart, they emit equal amounts of power in the form of 1.06m wavelength electromagnetic waves. (PHYS 1801 CL06) (a) Find the positions of the first, second, and third maxima of the received signal, as the detector D is moved along the x axis starting at 0. (b) Write an equation that you could use to find the location of any minima and find the position of at least one minimum on the x axis. y S2 d D x- 's ]oDescribe how the field radiated by an aperture can be determined from the Huygens Principle using a Fourier TransformMonochromatic beams are passed on the diffraction grid with a lattice count of 100 lattice/cm of light undergoes dark diffraction to three measured within 5.5 mm of light center, gap distance to the screen 40 cm.

- Determine the probability that a photon is detected at the location of the first minimum of a 3-slit grating if the thrid slit is closed. You can assume that the magnitude of the probability amplitude due to each slit is r. (Hint: Start by showing how the complex amplitudes from each slit add up to zero at the first minimum. What is the resulting amplitude if the first amplitude is eliminated?)Use the worked example above to help you solve this problem. A sodium surface is illuminated with light of wavelength 0.329 µm.
