Q. No.Time taken by sunlight to pass through a glass slab of thickness \(5~\text{mm}\) and refractive index \(1.5\) is:
1. \(\left(\dfrac{5}{3}\right) \times 10^{-8}~\text{s}\)
2. \(\left(\dfrac{5}{2}\right) \times 10^{-11}~\text{s}\)
3. \(\left(\dfrac{5}{3}\right) \times 10^{-11}~\text{s}\)
4. \(\left(\dfrac{5}{2}\right)\times 10^{-8}~\text{s}\)
1. \(\left(\dfrac{5}{3}\right) \times 10^{-8}~\text{s}\)
2. \(\left(\dfrac{5}{2}\right) \times 10^{-11}~\text{s}\)
3. \(\left(\dfrac{5}{3}\right) \times 10^{-11}~\text{s}\)
4. \(\left(\dfrac{5}{2}\right)\times 10^{-8}~\text{s}\)

NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyA beam of light is incident vertically on a glass slab of thickness \(1\) cm, and refractive index \(1.5.\) A fraction \(A\) is reflected from the front surface while another fraction \(B\) enters the slab and emerges after reflection from the back surface. The time delay between them is:
| 1. | \(10^{-10}\) s | 2. | \(5\times 10^{-10}\) s |
| 3. | \(10^{-11}\) s | 4. | \(5\times 10^{-11}\) s |
