What is reflection and refraction? Laws of reflection are refraction?

Question

Answer

Answer

Reflection and Refraction

Reflection

Reflection is the phenomenon in which light or any other wave is returned to the same medium after striking the surface of another medium. The surface that reflects the wave is called a reflecting surface.

Laws of Reflection

The laws of reflection are:

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

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

Refraction

Refraction is the bending of light or any other wave due to its change in speed when it passes from one medium to another. The speed of light is different in different media, so when light passes through a boundary between two media, it changes its direction.

Laws of Refraction

The laws of refraction are:

The incident ray, the refracted ray, and the normal to the surface of the boundary at the point of incidence all lie in the same plane.

The ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant for a given pair of media.

Conclusion

In conclusion, reflection and refraction are important phenomena in optics and have many practical applications. The laws of reflection and refraction help us to understand and predict the behavior of light and other waves when they encounter boundaries between different media.

Answer

Reflection involves a change in direction of waves when they bounce off a barrier. Refraction of waves involves a change in the direction of waves as they pass from one medium to another. Refraction, or the bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves              and The law of reflection states that, onreflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray
