Question

$\left(i\right)$ Name one factor that affects the lateral displacement of light as it passes through a rectangular glass slab.
$\left(ii\right)$ On reversing the direction of the current in a wire, the magnetic field produced by it gets ___________

Answer 1

$\left(i\right)$ The factors that affect the lateral displacement of a light as it passes through a rectangular glass slab are:
(1) The thickness of the glass slab: The lateral displacement increases with the increase in the thickness of the glass slab.
(2) The angle of incidence: It increases with the increase in the angle of incidence.
(3) The refractive index of glass: The wavelength of light used. (It is more for violet light than for the red light.)
$\left(ii\right)$ 'Reversed'
