A prism of refracting angle30° is coated with a thin film of transparent material of refractive index2.2 on face AC of the prism. A light of wavelength6600 Å is incident on face AB such that angle of incidence is 60°. Find\n\n(a) the angle of emergence and(b) the minimum value of thickness of the coated film on the face AC for which the light emerging from the face has maximum intensity.(Given refractive index of the material of the prism is3 ) 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
