Explanation 1) Concept: By using Bragg’s diffraction condition and from the given graph, we can find the shorter and the longer wavelength in the beam. 2) Formula: 2 d sin ⁡ θ = m λ 3) Given: i) Interplanar spacing, d = 0.94 n m ii) Horizontal scale, θ s = 2.00 ° iii) Order, m = 1 4) Calculations: a) By considering the graph from Fig. 36-46 and using the given horizontal scale, we can estimate that the first peak is at an angle 0.75 ° . So by Bragg’s diffraction condition for the first order, we can find the shorter wavelength of the beam. 2 d sin ⁡ θ 1 = λ 1 λ 1 = 2 × 0.94 × sin ⁡ 0.75 0 λ 1 = 2 × 0

Compton effect

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…

Recoil Velocity

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.
