The time-slit... WebAnswer: 1. Reflection occurs in a mirror when light rays hit the surface of the mirror and bounce back in the same direction. Refraction occurs when light passes through the mirror's surface and changes direction due to a change in the medium's density (e.g., air to glass).
WebRefractive Index (Index of Refraction) is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density. The refractive index …
