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.
Explain Gauss's law in electrostatics? 1C of charge is same to the charge of n number of electrons in magnitude. What is the value of n? What happens to the force between t
Illustrate a labelled diagram of Hertz's experimental set-up to produce electromagnetic waves. Describe the generation of- electromagnetic waves using this set-up.
a) Two charges of the value 15X10 -9 coulomb and 30X10 -9 coulomb are locate at a distance 6 cm. Determine the intensity of electric field at point which is at a distance 2 cm fro
