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

    half wave plate can change the direction of rotation of left handed elliptically or circularly polarised into respective right handed elliptically or circularly polerised light and vice versa.

    this is the complete explanation for the half wave plate .

    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 income and outgoing waves are Circularly polarized light with a phase difference of π(as the negative sign before iota in outgoing wave shows a phase change of π)

    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 polerised.

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

    i hope whatever i attached will explain u quarter wave plate completely.

    eduncle-logo-app

    if still have any doubt plz ask.

    eduncle-logo-app

    very simple explanation ma'am I appreciate you..
