When an object is moved along the principle axis of a concave mirror placed in air, the image coincides with the object if the object is \(50 \mathrm{~cm}\) from the mirror. If the mirror is placed at a depth of \(20 \mathrm{~cm}\) in a transparent medium, the image coincides with the object when the object is \(40 \mathrm{~cm}\) from the mirror. The refractive index of the liquid is
- A \(\frac{5}{4}\)
- B \(\frac{4}{3}\)
- C \(\frac{3}{2}\)
- D \(\frac{5}{3}\)
Answer & Solution
Correct Answer
(C) \(\frac{3}{2}\)
Step-by-step Solution
Detailed explanation
According to the question, an object is placed on the principle axis of a concave mirror is shown in the figure below, Since, it is given that, an object at \(50 \mathrm{~cm}\) from pole is act like, it placed at \(40 \mathrm{~cm}\) from the pole when mirror is placed inside a…
