Explain what happens to the coin in the water glass? The light emitted by the coin travels in a straight line through the water but is refracted at the boundary between water and air. This phenomenon is known as 'light refraction', causing the coin to appear displaced. What causes the peculiar appearance of the glass rod? Light rays from the rod reach the eye. Rays traveling through air spread faster than those passing through water, leading to light refraction at the interface between the two materials, making the rod appear broken.
