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.
It is based on the photovoltaic effect. One of the semiconductor regions is made so thin that the light incident on it reaches the p-n junction and gets absorbed. It changes solar
Motion of an object in a plane is called two dimensional (2-D) motions. For 2-D motion acceleration or velocity can be explained by two elements in any two mutually perpendicular d

Explain the term- Zener Breakdown Under a very high reverse voltage, depletion region expands and potential barrier increases resulting in a very high electric field (3X10 7
With the help of relevant diagrams, define the following terms: (i) Pulse-position modulation (PPM) (i) Pulse-duration modulation (PPM)
Q. Movement of principal ray? In every case a principal ray moves from the head of the object to the plane of the lens. It passes through the plane of the lens as well as conti
