Two parallel beams of light P and Q (separation d) containing radiations of wavelengths4000 Å and5000Å (which are mutually coherent in each wavelength separately) are incident normally on a prism as shown in figure.\n\nThe refractive index of the prism as a function of wavelength is given by the relation,μ(λ)=1.20+bλ2 whereλ is in Å and b is positive constant. The value of b is such that the condition for total reflection at the face AC is just satisfied for one wavelength and is not satisfied for the other.(a) Find the value of b.(b) Find the deviation of the beams transmitted through the face AC.(c) A convergent lens is used to bring these transmitted beams into focus. If the intensities of the upper and the lower beams immediately after transmission from the face AC, are4I andI respectively, find the resultant intensity at the focus. 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
