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.
Show any two applications of beats. What are "Echelon effects" and "Focusing"?
This depends on the arrangement of a beam or column. for a simply supported beam with a point load in the centre of the beam Mmax = WL/4 and will occur at centre span W is the lo
