Plese explain quarter & half wave plate in detail

A plane wave (? +iý)E, explilkz - ar)] after passing through an optical element emerges as(f-iý)E, explilkz - o). where k and o are the wavevector and the angular frequency, respectively. The optical element is a (a) quarter wave plate (c) polarizer (b) half wave plate (d) Faraday rotator

    yeah,the right ans is half wave plate as the only direction of vibration of e.f is changed ,nature of wave is not changing... that's why half wave plate is the option...

    The optical element used here is Half Wave Plate(HWP). As you can see, the incoming and outgoing waves hase same nature, except that the sign of Y component changes here. Both inco...

    when a plane polerised light is incident normally on a quarter wave plate and it's plane of vibration makes an angle 45° with the optics axis then the emergent light is circularly ...

    these plates are doubly refrecting crystal with uniform thickness.it creates path difference of lembda/4.
