Question

In case of a concave mirror when the object is at focus, the rays after reflection are parallel. So, how does the rays of light meet at infinity when they are parallel?

Answer 1

Answer:

we assume it to meet at some point

Explanation:

Answer 2

Answer:

In the Diagram given below:

Explanation:

⇒ The second ray AE passing through the centre of curvature C is reflected along the same path forming the reflected ray EY.

⇒ In this case, both the reflected rays i.e. DX and EY become parallel to each other so these rays cannot intersect each other and the image will be formed at infinity.
