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 difference among potential energy of two points A and B is described as equal to the amount of work done (by external agent) in moving a unit positive charge f
can u tell me wats d QD which has excitation at in the 980nm range?
