JEE Mains · Physics · STD 12 - 9. Ray optics and optical instruments
A concave mirror of focal length \(f\) in air is dipped in a liquid of refractive index \(\mu\). Its focal length in the liquid will be:
- A \(\mu f\)
- B \(f\)
- C \(\frac{f}{(\mu-1)}\)
- D \(\frac{f}{\mu}\)
Answer & Solution
Correct Answer
(B) \(f\)
Step-by-step Solution
Detailed explanation
Focal length of mirror will not change because focal length of mirror doesn't depend on medium.
