Physics
An object placed in one medium when seen from the other medium, appears to be vertically shifted. Name two factors on which the magnitude of the shift depends and state how does it depend on them.

Answer
The shift by which the object appears to be raised depends on —
(i) The refractive index of the medium — Higher the refractive index of the medium, more is the shift.
(ii) The thickness of the denser medium — Thicker the medium, more is the shift.
(iii) The colour or wavelength of incident light — the shift decreases with the increase in the wavelength of light used.

Assertion (A): A ray of light travelling from a rarer medium to a denser medium, slows down and bends away from the normal.
Reason (R): The speed of light is higher in a rarer medium than in a denser medium.
