A glass hemisphere of radius \(0.1 \mathrm{~cm}\) and refractive index \(1.5\) is placed over a spot on a table and the spot is viewed from above. The spot appears to be
- A \(0.1 \mathrm{~m}\) above the top surface of the hemisphere
- B \(0.1 \mathrm{~m}\) below the top surface of the hemisphere
- C \(0.033 \mathrm{~m}\) above the top surface of the hemisphere
- D exactly on the top surface of the hemisphere
Answer & Solution
Correct Answer
(A) \(0.1 \mathrm{~m}\) above the top surface of the hemisphere
Step-by-step Solution
Detailed explanation
Here, \(R=-0.1 \mathrm{~cm}, \mu_{g}=15\) \[ \therefore \quad u=-0.1 \mathrm{~cm} \] From refraction formula,…
