Compton effect (A.H. Compton; 1923)
An effect which demonstrates that photons (the quantum of electromagnetic radiation) contains momentum. At a stationary particle, a photon fired such as an electron, will impart momentum to the electron and, as its energy has been reduced, will experience a corresponding falling in frequency.
PHYSICS ASSINGMENT ELECTRON MICROSCOPY COMPONENT. PLEASE ANSWER THESE QUESTIONS WITH DEATALING AND referencing if it needed. many thanks
mole; mol The basic SI unit of substance, explained as the amount of substance which contains as many elementary units (molecules, atoms ions, etc.) as there are atoms in 0.01
Dimension of unit impulse DIMENSION ? The dimension of impulse is [MLT -1 ]
IMPULSE: When a force acts on a body for a very short time, the product of the force and the time for which the force acts, is called the impulse or impulse of force".

The Schottky diodes are a semiconductor diode with a low forward voltage drop and a very fast switching action. The voltage drop at forward biases of around 1ma is in the range 0.1
Start from the expression of the electric field outside an infinite sheet of uniform surface charge density, E = s/2epsilon, derive the electric field just outside an ideal conduct
The vapour pressure of a substance at 20.0 o C is 38.1 kPa and its enthalpy of vaporisation is 49.6 kJ mol -1 . Estimate the temperature at which its vapour pressure is 80.0 k
State Gauss's law. The total flux of the electric field E over whichever closed surface is equal to 1/ε o times the net charge enclosed by the surface. That is φ = q / ε
(1) These rays transmitted in the forward direction of medium with a finite speed. (2) Energy and momentum are transmitted in the direction of propagation of waves without real
