Conceptual Question about Polarisation and Intensity/

  1. Apr 18, 2016 #1
    1. The problem statement, all variables and given/known data
    Consider a beam of unpolarised light incident onto air from a crown-glass with a refractive index of 1.52.

    Given that the incident light intensity has a power of 10mW, find the minimum incident angle when the power of the refracted light becomes zero.

    2. Relevant equations
    I have no idea what equations can be used to solve this.

    3. The attempt at a solution
    From what I understand, the unpolarised light can lead to a reflected polarised beam and a refracted beam- this happens if the angle of incident is Brewster's Angle.

    I am guessing the power of the refracted light is zero if the reflected light is fully polarised?

    This is the second part of the question. First part asked for Brewster's Angle and the polarisation state(56.7degrees and Linear Polarisation)

    Hey John, you mind to show the steps done?

    Update: It's alright I figured it out. :)
