Find the Brewster angle of a wave transmitted from a medium of permittivity 4 to a medium of permittivity 2.(a) 35.26(b) 53.62(c) 26.35(d) 62.53I got this question by my college professor while I was bunking the class.This key question is from Brewster Angle topic in chapter EM Wave Propagation of Electromagnetic Theory |
Answer» CORRECT option is (a) 35.26 Best explanation: The Brewster angle is GIVEN by θb = tan^-1(n2/n1), where n = √ε. Thus we can express the formula in terms of PERMITTIVITY as θb = tan^-1√ (ε 2/ε 1). Here ε1 = 4 and ε2 = 2. Thus we get θb = tan^-1√ (2/4) = tan^-1(0.707) = 35.26 degree. |
