Double slit interference Two sets of coherent waves will interfere with each other producing INTERFERANCE patterns. This can be seen by allowing a set of waves to pass through a double slit.Nodal lines –destructiveinterference. SAMPLE ONLY SAMPLE ONLY
Single Slit Experiment This experiment proves that light undergoes ……………………….., and hence LIGHT is a ……………... A thin rectangular piece of glass is painted with black paint, and a thin single slit is made on the paint with a razor blade. White Light A beam of white light is shone through the slit. Observation 1) A broad …………………….. of bright white light is observed. 2) This is flanked by alternate spectral ……………….. and black fringes. What factors would affect the amount of diffraction?? How?? SAMPLE ONLY SAMPLE ONLY
Hygen’s Principle Every ………………… on the wave front acts as the ……………….. of a new wave. SAMPLE ONLY SAMPLE ONLY
Diffraction Light intensity NODE ANTINODE NODE Nodal lines appear in the diffracted waves. SAMPLE ONLY SAMPLE ONLY
m Diffraction Questions Sin = a1. Find the position of the first dark band formed on the screen when red light of wavelength 690 nm is passed through a slit of width 6.0 m.2. Compare this with the position of the first order dark band when blue light of wavelength 460 nm is used.1 Red light: = 690 x 10-9 m a = 6.0 x 10-6 m and m = 1 sin = (1)(690 x 10-9 )/(6.0 x 10-6) = sin-1 (0.115) 6.60o = 6.60 o 4.40o2 Blue light: = 460 x 10-9 m a = 6.0 x 10-6 m and m = 1 sin = (1)(460 x 10-9 )/(6.0 x 10-6) = sin-1 (0.077) = 4.40o SAMPLE ONLY SAMPLE ONLY
