The minimum number of rays required to locate the image formed by a spherical mirror is ______.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Two.
To locate the position of an image formed by a spherical mirror, a minimum of two rays originating from the same point on an object are required. This is because an image is formed at the specific point where at least two reflected rays actually intersect (real image) or appear to intersect (virtual image). While infinite rays strike the mirror, using two standard rays, such as one parallel to the principal axis and one passing through the focus, simplifies the geometric construction.
