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.
State and explain laws of transverse vibrations in stretched strings. Describe how do you verify them using sonometer.
Sol: The incident angle is 45 because the angle of reflection and angle of incident is equal.
