3. Question
1 pointsCategory: Science and TechnologyOptical fibre works on the principle of
Correct
Optical fibres works on the principle of total internal reflection (TIR), when light in incident at an angle greater than critical angle at one end, it gets refracted and gets incident on the interface of fibere and its coating. This makes light to suffer multiple total internal reflections.

6. Question
1 pointsCategory: Science and TechnologyConsider the following statements:
- It is an indigenously developed nuclear capable missile.
- It is a short range surface to surface missile.
- It is the first missile to be developed by DRDO under Integrated Guided Missile Development Programme.
The above properties refers to which of the following missiles?
Correct
Prithvi II is an indigenously developed nuclear capable missile. With a strike range of 350 km, the Prithvi-II is capable of carrying 500 kg to 1,000 kg of warheads and is thrusted by liquid propulsion twin engines. It uses advanced inertial guidance system with manoeuvring trajectory to hit its target. It is a short range surface to surface missile.
Inducted into Indian armed forces in 2003, the nine-metre-tall, single-stage liquid-fuelled Prithvi-II is the first missile to be developed by the DRDO under the Integrated Guided Missile Development Programme.
