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.

Vector Addition The Order Does NOT Matter The question frequent arises as to the significance of the order in that the vectors are added. For example, if five vectors are added
Derive an expression for the torque acting on a loop of N turns, area A, carrying current i, when held in a uniform magnetic field. With the help of ciruit, show how a moving coil
A bar magnet is overhanging north end up well above a vertical coil of wire. The bar magnet is released and as it falls down toward the coil it falls along a path that will take it
84.1grams of He are compressed reversibly and isothermal at 100.0C from 28.0Litre to 7.37Litres. Calculate the the entropy change in joules/K.
Refracting telescopes, if uncorrected, suffer from chromatic aberration. Chromatic aberration occurs because: a) red light is focused more strongly than blue light b)
A transparent glass cube, of side 20 cm has a small air bubble. When it is viewed normally from the nearest face it seems to be at 0.05 cm from that face and when it viewed throug
