   CONCEPT:

   • Refraction: The bending of a ray of light when it goes from one medium to another is called refraction of light.
     • Refraction occurs when waves or rays of the light bend towards or away from the normal when they travel from one medium to another of a different density.
     • When a light ray travels from a lighter to a denser medium, the light ray bends towards the normal.
     • When a light ray travels from a denser to a lighter medium the light ray bend away from the normal.

   

   EXPLANATION:

   1. Reflection: The phenomena in which light ray is sent back into the same medium from which it is coming, on interaction with boundary, is called reflection.
   2. Dispersion of light: The splitting of white light, when it passes through glass prism into its constituent spectrum is known as the dispersion of light.
   3. Refraction: The bending of light rays in the denser medium is termed as Refraction. So option 3 is correct.
   4. Deflection: There is no such phenomenon as a deflection of light.
