Question

A beam of incident parallel light falls on a diverging lens of focal length \(20\) cm in magnitude. If a converging lens of focal length \(15\) cm in magnitude is placed at a distance of \(10\) cm to the right of the diverging lens on the other side, then, the final image formed is:

• A. Virtual and is at a distance of 30 cm to the right of the converging lens.
• B. Virtual and is at a distance of 40 cm to the right of the diverging lens.
• C. Real and is at a distance of 30 cm to the right of the converging lens.
• D. Real and is at a distance of 40 cm to the right of the converging lens.

Hint:

For lens combinations, the image formed by the first lens acts as the object for the second lensUse sign convention carefully for each lens.

Answer 1

The Correct Option is C
