The two laws of reflection are:
(i) The angle of incidence is equal to the angle of reflection.
(ii) The incident ray, the normal to the mirror at the point of incidence, and the reflected ray all lie in the same plane.
What are the two laws of reflection that apply to all types of reflecting surfaces, including spherical surfaces?

The two laws of reflection that apply to all types of reflecting surfaces, including spherical surfaces, are:
1. The incident ray, the reflected ray, and the normal (a line perpendicular to the surface at the point of incidence) all lie in the same plane.
2. The angle of incidence (the angle between the incident ray and the normal) is equal to the angle of reflection (the angle between the reflected ray and the normal). Mathematically, θi = θr.
These laws are fundamental principles that govern the reflection of light and are applicable to various surfaces, including flat and curved surfaces like mirrors and spherical mirrors.
