The process of changing of a heavy nucleus into two lighter nuclei of comparable masses (after bombardment with a energetic particle) with liberation of energy is known as nuclear fission.
The phenomenon of nuclear fission was discovered by scientist Ottohann and F. Strassman and was exemplify by N. Bohr and J.A. Wheeler on the starting of liquid drop model of nucleus.
Is there any other proof that light is an electromagnetic wave other than its speed has the same value as the inverse square root of the permittivity and permeability constants of
Define the Intensity of the laser in short. Intensity: a. Lasers are intense and bright light sources. It is due to coherence and directionality. b. The intensity is e
The scattering of a photon by an electron is known as Compton Effect. The momentum and energy is preserved. Scattered photon will have less power as compare to incident photon (les

The photon fluence rate is 10 7 photons mm -2 sec -1 for a beam of γ rays. One fourth of the photons have energies of 100 keV, one half have energies of 80 keV and the remaining
Q. Show Constant Moment Arm? The simplest case is that of a point mass, and the moment of inertia can be immediately written as I = mR 2 ,
The earth "spins" (rotates) on its axis based on the action of the materials that accreted to form it, and also on any large collisions it might have undergone. Like the one in the
Q. What is neutral temperature? Maintain the temperature of the cold junction constant the temperature of the hot junction is gradually increased. The thermo emf increase to a
A thermal imager is used to measure the temperature of a target surface (ε = 1) in the test section of a wind tunnel. The thermal imager must view the target though a window. The t
