10Refraction is the bending of light when it passes from one medium to another.
Light bends away from the normal when entering a denser medium.
Lateral shift occurs when light passes through a parallel-sided slab.
The refractive index is the ratio of the speed of light in air to that in the medium.
The emergent ray is always parallel to the incident ray in a glass slab.
Snell’s law states sin i / sin r = constant for a pair of media.
Stars twinkle due to atmospheric reflection.
The apparent depth of a coin in water is less than its real depth.
Light bends towards the normal when going from rarer to denser medium.
The refractive index of diamond is less than water.
