Question
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 shift depends and state how does it depend on them.

Solution
The factors on which the magnitude of shift depends are:
- The refractive index of the medium,
- The thickness of the denser medium and
- The colour (or wavelength) of incident light.
The shift increases with an increase in the refractive index of the medium. It also increases with the increase in thickness of the denser medium, but the shift decreases with the increases in the wavelength of light used.
