White light is incident normally on a glass plate (in air) of thickness `500 nm` and refractive index of `1.5`. The wavelength (in `nm`) in the visibl

Correct Answer - B For strong reflection. `2mut=(lambda)/(2),(3lambda)/(2),(5lambda)/(2).....rArr lambda=4mut,(4mut)/(3),(4mut)/(5),(4mut)/(7).....` `rArr 3000 nm. 1000 nm, 600 nm, 333 nm.` `rArr` only option is `600 nm`.
