A photon hits a metal surface with known work function φ. Due to the photo-electric effect, an electron with mass me is ejected from the metal surface. The ejected electron has a wavelength e. Further, you may assume Planck's constant h and the velocity of light c to be known Express the wavelength of the photon ,h in terms of the quantities specified above. [10 pts]
19) when light of a wave length 0.4mm hits a metal with an electron binding energy of 2eV, electrons are ejected with a KE of? a) 1eV b) 2eV C)3eV d) 4eV e) 5eV
2. A photon strikes a piece of metal and an electron is ejected. The wavelength of the electron is 8.7 x 10-11 m - what is the kinetic energy of this electron? Answer
3 36. A photon with frequency 7.0 x 104 Hz is shined on a metal surface and ejected an electron with 2.19 x 1021J. Calculate the kinetic energy of the ejected electron? (5 points)
Briefly explain and show all work please A 3.2 ev photon hits a metal electrode with a work-function of 2.3 ev. What can be said about this situation? an electron is ejected from the surface with a positive Kinetic Energy an electron is ejected from the surface but has no Kinetic Energy an electron is ejected from the surface with a negative Kinetic Energy an electron is not ejected from the surface Which color of light has a greater amount...
If electrons are ejected from a metal when yellow light is shone on it, explain, using the photoelectric effect what will happen if: Infrared light was used. X-ray was used
When red light shines on a piece of metal, no electrons are released. When the red light is slowly changed to shorter-wavelength light (basically progressing through the rainbow), nothing happens until yellow light shines on the metal, at which point electrons are released from the metal. If this metal is replaced with a metal having a higher work function, which light would have the best chance of releasing electrons from the metal? If this metal is replaced with a metal...
calculate the wavelength and energy of a photon that is ejected from a hydrogen atom when the electron travels from n=6 to n=2. what kind of light is it?
A photon of blue light and a photon of red light are traveling in vacuum. The photon of blue light... A) has a smaller wavelength than a photon of red light and travels with the same speed. B) has a smaller wavelength than a photon of red light and travels with a greater speed.
Electrons are ejected from sodium metal by any light that has a wavelength shorter than 544 nm. What is the kinetic energy of an electron (in J) that is ejected from sodium by light with a wavelength of 325 nm?
