At the interface of two transparent media, light ray experiences both refraction and reflection. Does the angle of reflection de
pend on the angle of refraction? Can you demonstrate the effect of total internal reflection using the rectangular block? Explain your answer and support your answer with a drawing. In which case the shift of the light beam passing through the transparent block equals zero?

Answer:
No, the angle of reflection is independent on the angle of refraction. The total internal reflection is when the angle of incidence is more than the critical angle.
Explanation:
No, the angle of reflection is independent on the angle of refraction. The angle of reflection is only affected by the angle of incidence.
The total internal reflection is when the angle of incidence (I) is more than the critical angle (C). When the light ray pass through the rectangular block, with time, a critical angle will be formed when the refracted ray is exactly 90 degrees to the normal. As soon as the angle of incidence is more than the critical angle, a total internal reflection is formed (as shown in the attached figure).

Explanation:
THE GIVEN sheet can be taken as two horizontal force with surface charge density is
at one surface is ∈_1 =
at oher surface is ∈_2=
the magnitude of electric field due to surface charge is given as
So, electric field at P (2 CM below from surface is) = E_1 +E_2
