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.
The higher power level band is called as the conduction band. (i) It is also called as empty band of minimum energy. (ii) This band is partially filled by the electrons. (
Malus' law (E.L. Malus): The light intensity I of a ray along initial intensity I0 travelling by a polarizer at an angle theta among the polarization of the light ray & the po
