Given:
The angle of reflection is 25 degrees.
Required: Angle of incidence
Explanation:
Normal is perpendicular to the plane of the mirror.
The below figure shows the incident ray, normal, and reflected ray.
Here, the black line represents the plane mirror.
The green line represents the incident ray.
The yellow line represents the normal.
The red line represents the reflected ray.
According to the law of reflection, the angle of incidence is equal to the angle of reflection.
Thus, the angle of incidence will be
[tex]\angle i=\text{ 25}^{\circ}[/tex]Final Answer: The angle of incidence is equal to 25 degrees.
