He-Ne gas laser which produces monochromatic light of a known wavelength λ= 6.35 x 10^-7 m is used to calibrate a reflection grating in a spectroscope. The first-order diffraction line is found at an angle of 22° to the incident beam. How many lines per meter are there on the grating?

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 lights, the Compton effect is missing.
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.
