Home work 1: Beam of X- rays of A = 0.842A° is incident on a crystal at a grazing angle of 8.35 when the first Bragg's reflection occurs calculate the glancing angle for third order reflection. Home work 2: X- rays with wave length of 0.58 A° are used for calculating d(200) in nickel .The reflection angle is 9.5° when is the size of unit cell Home work 3: amsu The Bragg's angle corresponding to the first order reflection from (111) plane in a crystal is 30 when X- rays of wave length 1.75A° are used, calculate inter atomic spacing. Home work 4: Calculate the longest wave length that can analyses by a rock salt crystal of spacing d = 2.82 A° in the first order.

The incoming photons' energy must be in the range of an X-ray frequency to generate the Compton effect. The electron does not lose enough energy that reduces the wavelength of scattered photons towards the visible spectrum. As a result, with visible ligh…

The amount of backward thrust or force experienced by a person when he/she shoots a gun in the forward direction is called recoil velocity. This phenomenon always follows the law of conservation of linear momentum.
