70, An incoherent beam of light strikes a glass plate at normal incidence. It undergoes multiple reflections at the two edges before exiting the plate. The intensity reflection coeficient at each interface is R and the glass has negligible absorption. Neglecting interference effects, the ratio of the total reflected intensity to the incidence intensity is given by 2R (a)+R (b) R(2- R) (c)R (d) R IIISo 20121
