A light ray strikes a plane mirror with an angle of incidence of ${37}^{\circ }$ measured from the normal. Determine the angle of reflection.

A $12.0$ cm tall object stands in front of a plane mirror. What is the height of its image?

A $1.0$ m ruler lies perpendicular to a plane mirror, with its $100$ cm mark nearest the mirror. The $100$ cm mark is $20$ cm in front of the mirror. Determine the distance between the real $30$ cm mark and the image of the $70$ cm mark.

A ray strikes a plane mirror such that the angle between the incident ray and the reflected ray is ${96}^{\circ }$. What is the angle of incidence measured from the normal?

What is the key distinction between the actual path of reflected light and the construction lines used to locate a plane-mirror image?
