Bragg's law (Sir W.L. Bragg; 1912)
While a beam of x-rays strikes at crystal surface wherein the layers of atoms or ions are separated regularly, the maximum intensity of the reflected ray takes place while the complement of the angle of incidence, theta, the wavelength of x-rays, lambda, and the distance among layers of atoms or ions, d, are associated by the equation
2 d sin theta = n lambda,
Where n is an integer.
In an electric field a charge (Q) experiences a force F = QE. If charge is positive then force is directed in the direction of field whereas if charge is negative force acts on i
what the main defination of current? Electrical current is a measure of the amount of electrical charge transferred per unit time. It represents the flow of electrons through a
Malus' law (E.L. Malus): The light intensity I of a ray along initial intensity I0 travelling by a polarizer at an angle theta among the polarization of the light ray & the po
It is significant to denote the time interval to in which we are talking about average. In a given time interval t 1 to t 2 the average angular acceleration is defined as ,
Must all illuminator have forced ventilation? Usually yes, the exception being which with a massive construction that dissipate heat by transfer or radiation.
In these diodes electron and hole pairs are formed by junction photoelectric effect. That is the covalent bonds are broken by the EM radiations absorbed by the electron in the V.B.
