  • Q6
    What is meant by a polarized light?
    A light wave that has a mixture of different wavelengths
    A light wave that oscillates in a single plane
    A light wave that is scattered in all directions

  • Q7
    What is Malus's Law?
    The intensity of polarized light passing through a polarizer is proportional to the square of the cosine of the angle between the polarizer and the direction of polarization
    The energy of a photon is proportional to its frequency
    The angle of incidence equals the angle of reflection
    The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant

  • Q10
    When unpolarised light passes through a polarising filter what happens?
    It is reduced to half intensity
    It gains intensity
    It disappears
    It is unaffected
