Question

How many rays at least are required to obtain the image formed by a spherical mirror? Why?

✓

Answer

The image of an object, formed by spherical mirror, can be located by constructing a ray diagram.
For this, we may arbitrarily consider a large number of rays emanating from a point on an object but for the sake of clarity of ray diagram, it is more convenient to consider only two rays, as the intersection of at least two reflected rays gives the position of the image of the point on that object.
