Wave Function The space-time behaviour of each moving quantum mechanical particle can be described by a function. This function is known as wave function. It is generally denoted by ψ. It is also stated as the variable quantity...

The de-Broglie hypothesis is confirmed by the experiment conducted by G.P. Thomson in 1927. This G.P. Thomson experiment is the evidence for the electrons to behave as waves. G.P. Thomson performed experiments in which a narrow...
Scanning Electron Microscope (SEM) is an improved model of an electron microscope. SEM is used to study the three dimensional image of the specimen. Principle When the accelerated primary electron strikes the sample, it produces...
The heat which is flowing along the length of the bar (linearly) is called linear heat flow or rectilinear heat flow. Let us consider a long metal bar heated at one end and let us consider the flow of heat along x-axis as shown...
Thermal physics is the combined study of thermodynamics, statistical mechanics and kinetic theory. Thermodynamics is the branch of physics that describes and correlates the physical properties of macroscopic systems of matter and...
Bodies in series Let us consider a compound media like a slab or a wall made up of two different materials A and B having thickness x1 and x2 as shown in (Fig. 1) Fig. (1) Bodies in series Let the temperature of two end...
Universe is made up of radiation (light) and matter (particles). Light has a dual nature i.e., it possess both particle nature and wave nature. No single phenomena exhibit both particle nature and wave nature simultaneously...
A monochromatic beam of X-rays is produced from an X-ray tube and is made to pass through the slits S1 and S2. These X-rays are made to fall on a Carbon block ‘ C ‘ which acts as scatterer. A Bragg’s...
Different laws were proposed for explaining the energy distribution with respect to the wavelength. They are as follows: (i) Wien’s displacement law It states that the maximum energy density (or intensity) of radiation...
