Question

Snell’s law gives us a constant which reflects a property of a material. It is called _____.

  1. Reflection coefficient
  2. Rigidity 
  3. Refractive index 
  4. Reflective coefficient 

hintHint:

Snell's law gives a constant that explains the refractive index.

The correct answer is: Refractive index 


    Snell’s law gives us a constant which reflects a property of a material. It is called refractive index.
    • Snell's law explains the refractive index.
    • It says the relationship between the angle of incidence and the angle of refraction.
    • The formula is nsinθ1= n2 sinθ2 where n1 and n2 are the incidents and refractive indices and the θ1 and θ2 are the angles of incidence and refraction.
