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.
This is due to the surface tension of water. Because of the surface tension , the drop tends to have minimum possible surface area, and the shape which is possible with minimum su

Q. What is action of points (corona discharge)? What is its use? The seep out of electric charges from the sharp points on the charged conductor is known as action of points o
In certain ranges of a piano keyboard, more than one string is tuned to the same note to provide extra loudness. For example, the note at 110 Hz has two strings at this frequency.
