NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyThe speed of light in media \(M_1\) and \(M_2\) is \(1.5\times10^{8}\) m/s and \(2.0\times10^{8}\) m/s respectively. A ray of light enters from medium \(M_1\) and \(M_2\) at an incidence angle \(i.\) If the ray suffers total internal reflection, the value of \(i\) is:
| 1. | equal to or less than \(\text{sin}^{-1}\left (\frac{3}{5} \right )\) |
| 2. | equal to or greater than \(\text{sin}^{-1}\left (\frac{3}{4} \right )\) |
| 3. | less than \(\text{sin}^{-1}\left (\frac{2}{3} \right )\) |
| 4. | equal to \(\text{sin}^{-1}\left (\frac{2}{3} \right )\) |
