A point object is held above a thin equiconvex lens at its focus. The focal length is \(0.1 \mathrm{m}\) and the lens rests on a horizontal thin plane mirror. The final image will be formed at
- A infinite distance above the lens
- B \(0.1 \mathrm{m}\) above the center of the lens
- C infinite distance below the lens
- D \(0.1 \mathrm{m}\) below the center of the lens
Answer & Solution
Correct Answer
(B) \(0.1 \mathrm{m}\) above the center of the lens
Step-by-step Solution
Detailed explanation
As the lens is placed on a horizontal thin plane mirror. So due to role of plane mirror the image will be formed at the same point \(O\) above \(0.1 \mathrm{m}\) distance above the center of the lens.
