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.

Describe the numerical aperture in the optical fibre. Numerical Aperture: The numerical aperture is described as the sine of the acceptance angle. Therefore, Numerical
Q. Define: grating element. The combined width of a slit as well as a ruling in a plane diffraction grating is called as a grating element.
Inertia: the resistance an object has to a alter in its state of motion. Newton's first law of motion declares that force is NOT required to keep an object in motion. Slide
