1. The speed of light in media M1 and M2 is \[1.5\times 10^{8} m/s and 2.0\times 10^{8}\] respectively. A ray of light enters from medium M1 to M2 at an incidence angle i. If the ray suffers total internal reflection, the value of i is :
2. Assertion (A): In medical technology endoscopy, optical fibres are used to facilitate visual examination of internal organs of the body. Reason (R): Optical fibres are fabricated so that there should be very less absorption of light and hence no appreciable loss of light intensity.  
3. Assertion (A): In total internal reflection reflected light is in the phase with incident light. Reason (R): Reflecting surface is rarer in TIR.  
4. The speed of light in media $M_1$ and $M_2$ is $1.5 \times 10^8 m/s$ and $2.0 \times 10^8 m/s$ respectively. A ray of light enters from medium $M_1$ to $M_2$ at an incidence angle $i$. If the ray suffers total internal reflection, the value of $i$ is: (2010 Mains)
5. Assertion (A): Diamond in air shine brightly and when dipped in transparent oil, its shine reduces. Reason (R): Diamond shines due to multiple total internal reflections.
