Concept:
Reflection:

• The phenomena in which light ray is sent back into the same medium from which it is coming, on interaction with boundary, is called reflection.
• Laws of reflection: it states that angle of incident will be equal to angle of reflection for a ray of light reflected from plain polished surface

i.e., The angle of incidence $\left({\mathit{\theta }}_{\mathit{i}}\right)$ = Angle of reflection $\left({\mathit{\theta }}_{\mathit{r}}\right)$ Note:
The incident ray, the reflected ray, and normal to the surface of incidence always lies in the same plane as shown above.
Explanation:
According to the law of reflection, the angle of reflection must equal the angle of incidence for each ray.
