Basic Properties of Electric Charge
1. Additive Nature of Charge: The net charge on a body is the vector sum of all the charges distributed in whole of the body in different parts.
If q_{1}, q_{2}, ………. q_{n} are the charges on a body then net charge q = q_{1} + q_{2} + …. + q_{n}
Example A system containing +2q, -3q and +8q,
Total charge q = +5q.
2. Conservation of Charge: The net charge on a system remains constant, it may move in a different part of the system. A charge can neither be created nor can be destroyed.
e.g, Pair production = electron (-e) + proton (+e)
3. Quantization of Charge: The net charge on a body is integral multiple of basic charge e.
So q = +-e +-2e +- 3e +- ……
Ray Optics and Optical Instrument - Lateral Shift Expansion
From below figure, Let AB is an incident ray, incident on a glass plate of thickness BM2 is the normal. The ray reflects to the path BC in the glass plate, and at point this ray emerges out CD. If we draw un deviated path of incident ray, then it goes to the path BE. If we draw a perpendicular from point C on this ray, it meets at point K.
Ray Optics and Optical Instrument - Critical Angle and Total Internal Reflection
Critical Angle: When the ray of light goes from denser to rare medium, it bends away from the normal and as the angle of incidence in denser medium increases, the angle of refraction in rare medium also increases at a certain angle, then angle of refraction becomes 90°. This angle of incidence is called Critical Angle.
Formula, according to snell’s law
Total Internal Reflections: When angle of incidence exceeds the critical angle then light may come back into the same medium after reflection from interface. This phenomenon is called Total Internal Reflection.
Application of Total Internal reflection:
1. Mirage: There is the optical illusion in hot places or at cool solid road in summer days. This is due to total internal reflection. In this process the inverted image is produced, so a possibility of water is inverted but there is no such place of water.
The inverted image is formed due to the total internal reflection.
Reflection of the space above the earth is divided into the layers. The layers near to the earth surface are rare and optical density increase upward.
Hence, the ray of the light starts from point A’ of the tree goes several refractions from denser to rare and its incident angle increases regularly. At a particular incident angle becomes more than critical angle, the ray goes back external reflection and its image is seen by the observer at point A’.
2. Brillians of Diamond: The refractive index of diamond 2.42
Hence the critical angle
Due to small critical angle and the shape made by cutting, so that incident angle is always greater than Critical angle hence due to multiple total internal reflection, the transmitted light is more bright.
3. Optical Fibre: It has three parts.
Core
Construction: The centre wire is made of glass or quartz through which optical rays passes its refractive index. About 1-5 another material surrounding it is called Cladding. Its refractive index is less then the refractive index of the core. It is around 1.48. The whole combination is provided by plastic cover.
Working: When the signal of optical waves incident on an angle greater than critical angle, it gets total internal reflection. At the interface of core and cladding this way optical waves is transmitted from one place to another places.
Application:
4. Totally Reflection Prism: Totally reflection prism is isosceles prism which one angle 90° and other at 45° each.
Working: There are two types of internal reflection, 90 and 180 degrees. The refractive index of prism glass material is 1.5 and its critical angle 41.8°.
Ray Optics and Optical Instrument - Reversibility of Light
Law of Reversibility: When the ray of light reverse back to its own path after refraction and reflection, this phenomenon is called Reversibility.
Multiply both equation.
^{1}n_{2} X ^{2}n_{1} = 1
