3. When a ray of light goes from air to glass, it bends ………The normal
4. The speed of light is …… in glass then air 5. The absolute refractive index is always ….. then unity
6. The relative refractive index can be less then ………​

Answer 1

Answer:

The refractive index of a medium gives an indication of the light bending ability of the medium. When light travels from one medium to another, its velocity changes. The phenomenon of light bending at an interface when it passes from one medium to another is called refraction.
