Long Answer Type Questions : 1. Are laws of reflection valid for all kind of reflecting surfaces? If all parallel rays of light after reflection are not parallel, will it be failure of laws of reflection? Explain.

Explanation:
The laws of reflection require the angle of incidence and the angle of reflection to be the same and for the incident ray, the normal at the point of incidence and the reflected ray to all lie in the same plane. These two laws of reflection will be obeyed in a diffused reflection
Yes, the law of reflection is valid for all kinds of reflecting surface. It is obeyed whenever light reflects, no matter what the surface consists of. In case the parallel rays of light after reflection are not parallel then it's not due to the failure of the laws of reflection. It is caused due to irregularities in the reflecting surface.

More to know
The phenomenon of light bouncing off the surface is called Reflection.
The laws of reflection:
- The incident ray, the reflected ray and the normal to the surface of the mirror all lie in the same plane.
- The angle of incidence is equal to the angle of reflection.
