In an electron microscope we wish to study particle of diameter about 0.10 um. a) What should be the de Broglie wavelength of the electrons? b) Through what potential difference should the electrons be accelerated to have that de Broglie wavelength?
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.
Given:
Diameter of particle =0.10
a) In order to observe any object under electron microscope, the wavelength of electron used is to be of the same order as that the diameter of the particle to be observed.
So De Broglie wavelength
