Homework Help: Direction of oscillation of wave

  1. Sep 8, 2014 #1
    1. The problem statement, all variables and given/known data

    Can you explain why the for Y , the direction of reflection is in and out of page ? p/s : the wording is in the photo. so i think it's needless to retype it again .

    2. Relevant equations

    3. The attempt at a solution
    is it because for reflected ray, the ray will oscillate in and out of the page just as the reason (in your explaination above) ?
    for Z , the light ray is not reflected because of the incident light only vibrate up and down to the plane of incident , so the light ray which oscillate in and out of the page doesn't exist at all , so the light is unreflected?

    Don't see no "explanation above"...

    If you want to check any of this, take a glass plate, put on polaroid sunglasses and hold another between a lamp and the glass plate !

    Either that, or you google a few reflection polarization images...
