Bohr given a model for hydrogen molecule which is also applicable for some lighter atoms in which a one electron revolves around a stationary nucleus of positive charge Ze (known as hydrogen like atom)
Bohr's model is based on the following postulates.
(i) The electron can revolve only in particular discrete non-radiating orbits, named stationary orbits, for which total angular momentum of the revolving electrons is an integral multiple of
Stopping Distance of a Hot Wheels Car While the Hot Wheels car collides along with the box and skids to a stop, external forces do an important amount of work upon the car. The
Define Wave Length Wave Length : The distance travel by a wave during the interval in which the particle of the medium done on vibration is called wavelength
Inductors in dc circuits: If it is required to increases the value of inductance in a circuit, then two or more inductors may be connected in series. The total inductance then

Snell's Law: The ratio of sine of angle of incidence to the sine of angle of refraction is constant for all rays passing from one medium to another medium. That is Sini/Sinr
When wave emitted by a self luminous object is dispersed by a prism to get the spectrum, the spectrum is known as emission spectrum.
