Refractive Index
- The extent of the change in direction that takes place in a given pair of media is expressed in terms of the refractive index.
- It turns out that light propagates with different speeds in different media.
- The value of the refractive index for a given pair of media depends upon the speed of light in the two media.

Working
- When the current begins to flow, current flows through brush X, then A to B, B to C, C to D and then to brush Y and into the battery.
- Now applying Fleming's Left Hand Rule to wire AB, Current is along AB, Magnetic Field is as shown (North-> South), the motion of the wire is downwards.
- Now applying Fleming's Left Hand Rule to wire CD, Current is along CD, Magnetic Field is as shown (North-> South), the motion of the wire is upwards.
- The rectangular coil begins to move in the anti-clockwise direction
- Note that during anti-clockwise motion, the split rings and axle also move, whereas the brushes don't move.
- After half a rotation, Wire CD and Split ring Q moves to the left. Wire AB and Split ring P moves to right. Brushes X and Y donot move.
- Now applying Fleming's Left Hand Rule to wire CD, Current is along DC. (Battery -> Split ring Q -> DC , Magnetic Field is as shown (North-> South), the motion of the wire is downwards.
- Now applying Fleming's Left Hand Rule to wire AB, Current is along BA. (Battery -> Split ring Q -> DC --> CB -> BA --> Split ring P) , Magnetic Field is as shown (North-> South), the motion of the wire is upwards.
- So, again the coil rotates in the anti-clockwise direction.
- The reversal of current in the coil results in the continous rotation of the coil. The reversal of current is achieved by the commutator rings

The steps involved in generating electricity in a nuclear reactor are:
(i) The controlled fission of uranium-235 in the nuclear reactor produces a lot of heat energy.
(ii) Liquid sodium or C02 gas is pumped continuously through the pipes embedded in reactor. Sodium absorbs the heat energy produced in reactor.
(iii) The hot sodium is then passed into the coil of heat exchanger containing water. The water absorbs heat from hot sodium and gets converted into steam.
(iv) This steam at high pressure is used to rotate the turbine. The shaft of the turbine is connected to the electric generator. When turbine rotates, its shaft also rotates and drives the generator. The generator thus, produces the electricity.

- A food chain is a series of organisms where all the organismsare dependent on next organism as a source of food.
- The series of organism take part at various biotic levels to form a food chain.
- Each step of the food chain forms a tropic level.
- The producers (green plants) are at the first tropic level.
- Primary consumers (herbivores) are at the second tropic level.
- Secondary consumers (small carnivores) constitute the third tropic level.
- Tertiary consumers (larger carnivores) form the fourth tropic level.
