2. Ciliary muscles are responsible for accommodation of the eye.
3. The number of images formed depends upon the angle between the mirrors.

Answer 1

2. This is helpful in effort to make focus on near objects clearer. Three reactions occur simultaneously; the eyes adduct, the ciliary muscles contract, and the pupils become smaller. This action involves the contraction of the medial rectus muscles of the two eyes and relaxation of the lateral rectus muscles.

3. The number of images formed by two adjacent plane mirrors depends on the angle between the mirror. If (in degrees) is angle between the plane mirrors then number of images are given by, n = 360 θ − 1.
