Section B

Q1. Using the Fermat's principle, mathematically derive the laws of refraction. दीर्घवृत्त, जिनकी दो विद्युत तरंगे \textEx और \textEy, क्रमशः x और y दिशाओं में ध्रुवीकृत है और जिनके बीच \varepsilon 2.7 सापेक्ष कलांतर तथा z दिशा में संचरित हो रही है, का सामान्यीकृत समीकरण को गणितीय रूप से सिद्ध करिए। इस समीकरण की सहायता से, आगे एक दीर्घवृत्त, वृत्त और सीधी रेखाओं के समीकरणों को सिद्ध करिए। [40] Mathematically derive the generalized expression of an ellipse for two electric waves Ex and Ey polarized along x and y direction, respectively, and have a relative phase difference ε between two waves which are propagating along z-direction. From this expression further derive the equations for an ellipse, circle and straight lines. FRO3-PH [2]
