c) Show that the Irradiance of an electromagnetic wave travelling in a medium with refractive index n is given by the expression: 1 = vegn? JER 1 2 where the symbols have their usual meaning. [6 marks) d) The electric field of a light wave travelling through a vacuum has an amplitude of 150 Vm ! Calculate the amplitude of the Poynting vector [2 marks) What is the average radiation pressure associated with this light wave, assuming it is incident on a perfectly absorbing surface. [2 marks]
