000A wavelengths Interconnected 11. Two parallel Prakash Punj and Ham 4000A and 50008 Are radiations (which are different in each wavelength And these are incidentally incident on a prism. Of prism Can be given by the following equation as a function of. Refractive index of prism, sine = 0.8 86900 n (A) = 1.20 + 0 Where 2 is in A and b is a positive constant. The value of b is as follows. 1 For a wavelength the condition of complete reflection on the panel AC is met exactly. Whereas the second wavelength is not met. (a) Find the value of b. (b) Find the deviation of the transduced components from the pane AC. (c) The transduced bridges are brought into focus by a converging lens. If Intensities of upper and lower sides respectively after passing through AC If / and then find the resultant intensity at focus. (1991, 27- 12.n a layer of refractive index
