which of the following options is correct?
An EM wave from air enters a medium. The electric fields are E1 = E01 x cos [ 2 pie v { z/c – t } ] in air and E 2 =E 02 x ^ cos[k(2z−ct)] in medium, where the wave number k and frequency v refer to their values in air. The medium is non-magnetic. If ϵ r 1 and ϵ r 2 refer to relative permittivities of air and medium respectively, which of the following options is correct?
