Perry O’tic wanted to look at the atomic emission spectrum of Helium. He created a spectroscope with a diffraction grating (4900 lines per cm) and two metersticks. The diffraction grating was located 23 cm from the optical slit. When Perry O’tic looked through the diffraction grating, he observed a spectral line 8.0 cm from the optical slit. What is the wavelength of the observed spectral line?
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.
