Question

law of reflection and refrection​

Answer 1

Answer:

Law of reflection:

1. Angle of incidence is always equal to the angle of reflection.

2. The incident ray, the normal ray and the reflected ray all lie in the same plane.

Law of refraction:

1 . The incident ray, the refracted ray and the normal ray to the interface of 2 transparent Media at point of incidence, all lie in the same plane.

2.The ratio of sin of angle of incidence to the sine of angle of refraction for light of given colour is constant.

Answer 2

Laws Of Refraction Of Light:-

• The incident ray, the refracted ray and the normal to the interface of two media at the point of incidence all lie in the same plane.
• For the light of a given color and for given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant.

Laws Of Reflection Of Light:-

• Incident ray, reflected ray and normal to the surface of the mirror all lie in the same plane.
• The angle of reflection is equal to the angle of incidence. Both angles are measured with the respect to the normal to the mirror.
