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 think it is same as the apex angle of the prism or the angle of the prism. since it decides the angle of deviation as i+e=D+A(angle of the prism),D=deviation.
what is the magnetic field at a distance l from the centre of the circle of radius r which carries a current i
Example of an impure spectrum
Determine an expression for the current in the ring jumping ring demonstration, an electromagnet provides magnetic field of B=0.2 cos 377t tesla over a circle of radius 1.2cm
