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
If a negative charged particle enters a magnetic field perpendicularly,then it follows a circular path.In what directn does the particle move---in clockwise or anticlockwise? So
Demerits of Semiconductor Diode over Vacuum Diode (i) It can't withstand high reverse voltage (ii) It can't operate at fairly high temperatures.
tau-theta paradox (1950s): While two distinct types of kaons, tau & theta (today tau is a completely different particle) decay, tau decays in three particles, whereas the thet
There are two major differences between "center of gravity" and "center of mass": 1) The term "center of gravity" aplies to the bodies with mass and weight, while the term "cent
with the aid diagram, explain what meant by moment of force
what is the physics principle involved in the lens maker equation
If a traveling wave is a sin or cos function of (x± vt) the wave than it is said to be harmonic or plane progressive wave.
Within the elastic region (see the graph below), there exist a between the force applied and the change in the physical state of object. Experiments have shown that the elastic beh
write bernoulli,s equation using pressure,energy,and heads.
It is based on the principle that conductivity of a semiconductor enhances with increase in the intensity of incident light. In this, a thin layer of some semiconductor (as
