Ehrenfest paradox (Ehernfest, 1909)
The special relativistic "paradox" including a quickly rotating disc. As any radial segment of the disc is perpendicular to the direction of motion, there must be no length contraction of the radius; though, since the circumference of the disc is parallel to the direction of motion, it has to contract.
Explain about the single mode fibres in intermodal dispersion. Into single mode fibers, the core size of the fibre is decreased to 3 to 9µm so that this supports simply axial m

Explain, with the help of a circuit diagram, how the thickness of depletion layer in a p-n junction diode alters when it is forward biased. In the following circuits which one of t
Planck constant; h: The fundamental constant equivalent to the ratio of the energy of a quantum of energy to its frequency. It refer to the quantum of action. This contains th
Molecules: Let us take a piece of matter, for example, a drop of water and see what happens when it is sub-divided into smaller and smaller portions. The drop is first cut
GYROSCOPES: PRINCIPLES Gyroscopes are rotating masses (usually cylindrical in form) which are deliberately employed because of the particular properties which they demonst
Sol: The incident angle is 45 because the angle of reflection and angle of incident is equal.
Heat is the energy that is operated because of differences in temperature among the body and the surrounding. The unit of heat energy is Joule. The basic difference among study
