Question

Study the following ray diagrams:
The diagrams showing the correct path of the ray after passing through the lens are:

• A. II and III only
• B. I and II only
• C. I, II and III
• D. I, II and IV

Answer 1

The correct option is C I, II and III

All the incident rays parallel to the principal axis pass through the focus of the lens after refraction and vice-versa.

Thus diagrams $II$ and $III$ are correct.

Also the ray through the optical center of the lens passes undeviated i.e diagram $I$ is correct.

Thus option C is correct.
