A bubble in glass slab (\( \mu = 1.5 \)) when viewed from one side appears at 5 cm and 2 cm from otherside, then the thickness of the glass slab is:
- A 2.5 cm
- B 7.5 cm
- C 10.5 cm
- D 17.5 cm
Answer & Solution
Correct Answer
(C) 10.5 cm
Step-by-step Solution
Detailed explanation
\(T = (d_{1,app} + d_{2,app}) \times \mu\) \(T = (5 + 2) \times 1.5\) \(T = 7 \times 1.5\) \(T = 10.5 \text{ cm}\)
