Hint: By using the second law of reflection, The second law of reflection states that the angle of incidence is always equal to the angle reflection. Therefore, the angle of reflection is the same because the angle of incidence.
Complete step by step answer:
First Law of reflection: A ray of light is incident towards a plane mirror at an angle of \[{30^ \circ }\] with the mirror surface. The angle of reflection is ${60^ \circ}$. Same time the angle of incident is not \[{30^ \circ }\]; it is ${60^ \circ }$ since the angle of incidence is measured between the incident ray and the normal.
Second law of reflection: Consistent with the second law, the angle of reflection is usually adequate to the angle of incidence. This ray of sunshine is going to be reflected back along on an equivalent path. Objects and images. Anything which gives out its own reflection by it is called an object.
The incident ray will have an angle of reflection of \[{30^ \circ }\] note that is made with a surface normal to the mirror surface. The reflected ray will make an angle of ${60^ \circ }$ with the mirror surface, $({90^ \circ } - {30^ \circ })$.
Additional information:
Definition: Angle of incidence and Angle of reflection,
The angle between the incident ray and normal is understood because of the angle of incidence. The angle between the reflected ray and therefore the normal is understood because of the angle of reflection.
Note: The relationship between angle of reflection and angle of incident:
The angle between the incident ray and therefore the normal is understood because of the angle of incidence. The law of reflection states that when a ray of sunshine reflects off a surface, the angle of incidence is adequate to the angle of reflection.
