The group delay of a wave with phase constant 2.5 units and frequency of 1.2 radian/sec is(a) 3.7(b) 1.3(c) 3(d) 2.08The question was asked in an international level competition.My doubt is from S and P Polarised Waves topic in chapter EM Wave Propagation of Electromagnetic Theory |

Answer» RIGHT answer is (d) 2.08 For EXPLANATION: The group delay is given by td = β/ω. On SUBSTITUTING for β = 2.5 and ω = 1.2, we GET the group delay as td = 2.5/1.2 = 2.08 units. |
