Question

state the 2 laws of reflection and refraction​

Answer 1

Answer:

Reflection and refraction. ... The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray.

Answer 2

Answer:

laws of refraction states:

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

2)The ratio of the sine angle of incidence and ratio of sine angle of refraction is constant for the pair of given media this constant is called refractive index of second medium with respect to the first medium.

laws of reflection states:

1) The angle of reflection is equal to the angle of incidence.

2) The incident ray,the reflected ray and the normal at the point of incidence lie in one plane.The return of a sound wave on striking amsurface such as a wall,metal sheet , plywood etc back in the same medium is called the reflection of sound wave.
