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.

Positive rays are sometimes called as the canal waves. These were found by Goldstein. If the cathode of a discharged tube has holes in it and the pressure of the gas is around 10-3
Semi conductors: Semi conductors are these substances which lie among conductor and insulators. Semi conductor is those substances which hardly pass electric current by them
DECADE resistors are wire wound resistors. These are wound on cards moulded on round a switch of low contact resistance. Alloys used for wire are Manganin, minalpha, etc. Bifilar w
