Question 5

A student observes that when a coin is placed at the bottom of a beaker filled with water, it appears to be raised from its actual position. This phenomenon is primarily due to:

Accepted Answer

C. Refraction of light as it passes from water to air. — The apparent raising of an object submerged in water is a classic example of refraction. Light rays from the coin travel from water (denser medium) to air (rarer medium), bending away from the normal. This bending makes the light appear to originate from a shallower position to the observer's eye. Option A (reflection) causes images but not this specific apparent depth change. Option B (total internal reflection) would prevent light from exiting the water if the angle is too large. Option D (dispersion) is the splitting of light into colors, which is unrelated to the apparent depth phenomenon.

Answer

A. Reflection of light from the water surface.

Answer

B. Total internal reflection within the water.

Answer

D. Dispersion of light by the water molecules.
