B6.) In the photoelectric effect a photon of wavelength 2 imparts all of its energy to a free electron in a metal. Assume an incident photon has a wavelength of 440 nm. (a) What is the color? (b) What is its energy? (C) Find the wavelength of an electron after absorbing the photon (d) Suppose the separation potential between the electron and the means surface is 1V. What will be the wavelength of the electron upon emergence from the metal?
A hydrogen atom makes a transition from the n 55 state to the ground state and emits a single photon of light in the process. The photon then strikes a piece of silicon, which has a photoelectric work function of 4.8 eV. Is it possible that a photoelectron will be emitted from the silicon? If not, why not? If so, find the maximum possible kinetic energy of the photoelectron
6) Describe the process of crossing over and synapsis in detail. IN DETAIL PLS THANK YOU
In a photoelectric effect experiment, a photon with energy of 1.25x10-18J is absorbed, causing ejection of an electron with kinetic energy of 2.55x10-19J. a. Determine the wavelength (in nm) associated with the absorbed particle. b. Determine the wavelength (in nm) associated with the emitted particle.
A hydrogen atom initially in its ground state i.e., n= 1 level, absorbs a photon and ends up in n= 3 level. What must have been the frequency of the incident photon? (b) Now the electron makes spontaneous emission and comes back to the ground state. What are the possible frequencies of the photons emitted during this process?
QUESTION 69 How much more likely is a photoelectric interaction with bone (ZEff 13) than with soft tissue (ZEff 7.3) ? Round your answer to one decimal place 1 points Save Answer
suppose an atom absorbs a single photon and then gives back the energy of that photon in two successive transition. one transition produces a photon of 400nm, and the second transition produces a photon of 200nm. what is the wavelength in nm, of the original photon?
