What is the cutting potential of the ejected electrons when shining a monochromatic light with a wavelength of 400 nm on a metal whose work function is 2.0 eV? What is approximately the maximum velocity of the ejected electrons? ( ) 1.1 V and 620 km/s ( ) 2.0 V and 840 km/s ( ) 5.1 V and 1330 m/s ( ) 3.1 V and 1040 km/s ( ) 5.1 V and 1330 km/s
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.
