A travelling micros dot marked on a pi slab \((\mu=1.5)\) of thic the ink dot. The tra be moved in focus.
- A \(0.04 \mathrm{~m}\), downwards
- B \(0.04 \mathrm{~m}\), upwards
- C \(0.06 \mathrm{~m}\), downwards
- D \(0.06 \mathrm{~m}\), upwards
Answer & Solution
Correct Answer
(B) \(0.04 \mathrm{~m}\), upwards
Step-by-step Solution
Detailed explanation
We know that, Refractive index, \(\mu=\frac{\text { Real depth }}{\text { Apparent depth }}\) Here, \(\mu=1.5\) and real depth \(=\) thickness of glass \(\mathrm{slab}=0.12 \mathrm{~m}\) \(\therefore \quad \mu=\frac{012}{\text { Apparent depth }}\) Apparent depth…
