The convex mirror forms virtual, erect and diminished image of the object and rearview mirror also form some type of image.
Therefore, magnification (m) produced by a rear view mirror fitted in vehicles is less than one i.e., m < 1.
Magnification (m) $=\frac{\text{Image height}}{\text{Objects height}}$

    In an experiment with a rectangular glass slab, a student observed that a ray of light incident at an angle of $55^{\circ}$ with the normal on one face of the slab, after refraction strikes the opposite face of the slab before emerging out into air making an angle of $40^{\circ}$ with the normal. Draw a labelled diagram to show the path of this ray.' What value would you assign to the angle of refraction and angle of emergence?
