### Refraction of Light through a Glass Slab**Question:**A beam of light traveling in air strikes a glass slab at an angle of incidence less than 90°. After entering the glass slab, what does the beam of light do? (There could be more than one correct choice.)- [ ] It bends away from the normal at the point of contact.- [ ] It slows down.- [ ] It follows the normal to the glass slab.- [ ] It bends closer to the normal at the point of contact.**Explanation:**When light passes from air (a less dense medium) into glass (a more dense medium), it will undergo refraction:1. **It slows down**: Light travels slower in glass than in air due to the higher optical density. 2. **It bends closer to the normal at the point of contact**: As the light enters a denser medium at an angle, it bends towards the normal line (an imaginary line perpendicular to the surface at the point of contact).These principles are governed by Snell's Law, which describes how light rays change direction when passing through different media.

When light travels from one medium to another then ; When denser to rarer then it bends away from normal . When a light travel from rarer to denser medium it bends towards normal . Also , there is change in speed of light accordingly . That is ; From denser to rarer travels fast. From rarer to denser travel slow down .air is rarer and glass is denser medium as compared to air ,so , Correct option are (B) it slows down . (D) It bends closer to the normal at the point of contact .
