Detailed Solution

Concept- The phenomenon of an item reflecting light is known as reflection. If the surface is glossy and smooth. This is known as specular reflection.
Light, as we all know, has a pretty predictable behaviour. A ray of light approaching and reflecting off a flat mirror would obey a predictable law known as the reflection.
In other terms, a reflection of light is the process through which light rays fall on a surface and are reflected back into the same medium.
Almost everything reflects light, and this light enters our eyes, allowing us to see the objects. In general, each type of mirror, whether planar or spherical (concave and convex), has a shining surface that reflects light. This means that all mirrors produce images based on the reflection principle.

Reflection Laws:
1. The angle of incidence equals the angle of reflection.
2. The incident ray, the mirror's normal at the point of incidence, and the reflected rays are all in the same plane.
These reflection principles apply to every type of reflecting surface, including spherical mirrors.
Hence, the correct answer is option 3.
