JEE Mains · Physics · STD 12 - 9. Ray optics and optical instruments
An upright object is placed at a distance of \(40\, cm\) in front of a convergent lens of focal length \(20\, cm\). A convergent mirror of focal length \(10\, cm\) is placed at a distance of \(60\, cm\) on the other side of the lens. The position and size of the final image will be
- A \(40\, cm\) from the convergent mirror, same size as the object
- B \(20\, cm\) from the convergent mirror, same size as the object
- C \(40\, cm\) from the convergent lens, twice the size of the object
- D None of these
Answer & Solution
Correct Answer
(D) None of these
Step-by-step Solution
Detailed explanation
There will be \(3\) phenomenon \((i)\) Refraction from lens \((ii)\) Reflection from mirror \((iii)\) Refraction from lens After these phenomena. Image will be on object and will have same size. None of the option depicts so this question is Bonus. \(1^{\text {st }}\) refraction…
