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.
(i) The procedure of ejection of electrons from a metal surface by the application of heat is known as thermionic emission and emitted electrons are known as thermions and current

What is a good physics project?
One source of a star's energy is the fusion of two deuterons to form an alpha particle plus a gamma ray. a. Write down the nuclear equation for this fusion. b. Measure the m
p-type semiconductor: Consider a trivalent impurity such as Gallium (Ga, Z = 31) is doped in a pure semiconductor germanium (Ge, Z = 32). Each Ga atom forms three covalent bonds
what is deforming force
why The magnitude of known potential difference must be greater than the value of unknown potential difference to be measured.
