  • Question 1
    4 / -1

  • Question 2
    4 / -1

    When an unpolarized light of intensity I0 is incident on a polarizing sheet, the intensity of the light which does not get transmitted is

  • Question 3
    4 / -1

    When unpolarised light beam is incident from air onto glass (n = 1.5) at the polarising angle

  • Question 4
    4 / -1

    An optically active compound

  • Question 5
    4 / -1

    The Brewster angle for the glass-air interface is 54.74°. If a ray of light going from air to glass strikes at an angle of incidence 45°, then the angle of refraction is
    (Hint : tan 54.74° = √2)

  • Question 6
    4 / -1

    A beam of natural light falls on a system of 5 polaroids, which are arranged in succession such that the pass axis of each polaroid is turned through 60° with respect to the preceding one. The fraction of the incident light intensity that passes through the system is

  • Question 7
    4 / -1

    A plane electromagnetic wave travelling along the X-direction has a wavelength of 3 mm. The variation in the electric field occurs in the Y-direction with an amplitude 66 Vm–1. The equations for the electric and magnetic field as a function of x and t respectively
