why the light reflect in air short answer plz
Answers
Explanation:
Light waves are refracted when crossing the boundary from one transparent medium into another because the speed of light is different in different media. ... The distance between wave fronts will therefore be shorter in the glass than in air, since the waves travel a smaller distance per period T.

Explanation:
Reflection of light (and other forms of electromagnetic radiation) occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface.Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density) . This change of direction is caused by a change in speed. For example, when light travels from air into water, it slows down, causing it to continue to travel at a different angle or direction .The bending of light as it passes from one medium to another is called refraction. The angle and wavelength at which the light enters a substance and the density of that substance determine how much the light is refracted. ... The bending occurs because light travels more slowly in a denser medium .
