A ray of light parallel to the principal axis will pass through which point in case of mirrors?

Q. A ray of light parallel to the principal axis, after refraction passes through the focus of a convex lens.

Q. Any ray of light on passing through the principal focus of a concave mirror after reflection travels parallel to the principal axis.

Q. A light ray passing through the focus is incident on a concave mirror. It is reflected parallel to the principal axis.

Q. The figure shows a ray of light incident on a convex lens, parallel to its principal axis. Obviously the emergent ray passes through the principal focus F. Which of the following statements is correct?

Q.

For an incident ray directed towards centre of curvature of a spherical mirror, the reflected ray :

(a) retraces its path

(b) passes through the focus

(c) passes through the pole

(d) becomes parallel to the principal axis.
