Refraction of Light Experiment: Why a Coin Appears Raised in Water #3498589 (License: Personal Use)

This diagram illustrates the principle of refraction: light rays traveling from the coin through water into air bend at the interface, altering the apparent position of the coin. An observer’s eye perceives the coin along the extended path of the refracted ray, making it seem higher than its actual location. The labeled ray path and eye position clarify the geometric optics involved.
