1.	A coin is places at the bottom of a beaker containing water (refractive index = 4/3) to a depth of 12 cm. By what height the coin appears to be raised when seen from vertically above?
Answer» Refractive index of the water, μ_w = 4/3 Real depth at which the coin is places = 12 cm Shift in the image = ? Shift = real depth × (1 - 1/μ) Shift = 12 × (1 - 3/4) R = 12/4 = 3cm

A coin is places at the bottom of a beaker containing water (refractive index = 4/3) to a depth of 12 cm. By what height the coin appears to be raised when seen from vertically above?

Answer»

Refractive index of the water, μ_w = 4/3

Real depth at which the coin is places = 12 cm

Shift in the image = ?

Shift = real depth × (1 - 1/μ)

Shift = 12 × (1 - 3/4)

R = 12/4 = 3cm
