ELASTIC COLLISION:
"The collision in which both linear momentum and K.E are conserved is said to be elastic collision".
OR
"In the ideal case when no K.E is lost, the collision is said to be perfectly elastic".
For instance, when a hard ball is dropped onto a marble floor, it rebounds to very nearly the initial height. It loses negligible amount of energy in the collision with the floor.
An x-ray photon collides with a free electron, and the photon is scattered. During this collision there is conservation of: a) Momentum but not energy b) Neither momentu
A weakly guiding fibre with a particular graded core index has cut-off V-values for its 2nd, 3rd and 4th modes of 2.5, 3.9 and 5.2, respectively. The core radius is 4 microns, the

Defects of Vision Long Sightened When a person can see far objects clearly but cannot see near object clearly then this defect of vision is called as long sightedness.
The potential difference across the terminals of a cell when it is not supplying any current is known as it's emf.
Q. The kinetic energy of an electron 120 eV. Compute the de Broglie wavelength of electron. λ = h / √2mE λ = 6.626 X 10 -34 / √ 2 X 9.1 X 10 -31 X 120 X 1.6 X 10 -19
