Refraction of light

Ans: The degree of bending is determined by two factors: Change in speed – if a material causes light to refract (bend) more, it will do so. The angle of incident ray – the amount of refraction will be more evident if the light enters the substance at a larger angle.

Ans: Refraction is a key feature of lenses that allows them to concentrate a beam of light on a single point, and it’s also responsible for a number of well-known phenomena including the apparent deformation of objects partly submerged in water.

Ans: The refractive index’s value is influenced by two factors:

Temperature – The refractive index is commonly calculated at room temperature.

Light’s wavelength – Because various wavelengths interact with the atoms of the medium to varying degrees, the refractive index changes linearly with wavelength.

Ans: In refraction, wave speed, frequency, and wavelength are all important. Despite the fact that the wave slows down, its frequency remains constant due to the reduced wavelength.
