364941 An endoscope is employed by a physician to view the internal parts of a body organ. It is based on the principle of

1 Total internal reflection
2 Reflection
3 Dispersion
4 Refraction

364942 The critical angle for total internal reflection in diamond is \(24.5^{\circ}\). The refractive index of the diamond is

1 2.45
2 1.41
3 2.59
4 1.59

364943 A plane mirror is placed at the bottom of a tank containing a liquid of refractive index \(\mu \). \(P\) is a small object at a height \(h\)above the mirror. An observer \(O\) vertically above \(P\) outside the liquid sees \(P\) and its image in a mirror. The apparent distance between these two will be

1 \(\frac{{2h}}{\mu }\)
2 \(h\left( {1 + \frac{1}{\mu }} \right)\)
3 \(2\mu h\)
4 \(\frac{{2h}}{{\mu - 1}}\)
