question

If E = 5 volts/meter is the amplitude of an incident plane wave which is reflected at normal incidence from a boundary surface and E_1 is the amplitude of the reflected wave, find: (a) Under what conditions is there a pure standing wave? (b) The standing wave ratio when E_1 = 1/10 volt/meter. (c) The value ofE_maxandE_minwhen E_1 = 3/5 volt/meter.
