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.
In an electric field rate of change of potential with distance is called as potential gradient. It is a vector quantity and its direction is differing to that of electric field. Po

What is the mass ms of one 294Uus atom, in SI units? Include the error bars in your answer, using 1 atomic mass unit 1u = (1.66053892 ± 0.00000007) × 10-27 kg.
What is the relationship among the period and the square root of the length? The graph is linear, so the period is proportional to the square root of the length of the string.
