Differentiate between reflection and refraction​

Answer 1

Reflection:-

Whenever a ray of light comes back into the same medium after striking the surface of another medium then the phenomenon is called reflection of light.

Laws of reflection:-

1.The incident ray, the reflected ray, and the normal at the point of incidence all lie in the same plane.

2.The angle of incidence is equal to the angle of reflection.

Refraction:-

The change of direction and speed of light as it enters from one medium to another is called the refraction of light.

Laws of Refraction:-

1.The incident ray, refracted ray and normal ray at the point of incident lie in the same plane.

2.The ratio of Sin of the angle of incidence and sin of the angle of refraction is equal to constant. This constant is known as the refractive index. This is concluded by a Scientist called Snell, therefore it is also called Snell’s law.
