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.
Characteristics of resistances connected in parallel

actually in my college we are going to celebrate department function for physics we have to keep demos in physics for a project but i don''t have any idea will u help me
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
