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.
Laws of Refraction: There are two laws of refraction. The incident ray, the refracted ray and the normal to the surface of the point of incidence all lie at the similar plan

A standing wave is described by the wave function where x and y are in meters and t is in seconds. (a) Prepare graphs showing y as a function of x for five instants: t = 0, 5 ms,
The operation of a logic gate or circuit can be shown in a table which have all possible inputs and their corresponding output is known as the truth table. To write the truth table
Can fiber be made any size? Well theoretically, yes. However, there are physical constraints due tothe materials and utility. Extremely large fibers have proportional bending r
