A photon absorbed by an electron will give up more energy to the electron if the...
A photon of wavelength 80 nm is absorbed by the electron in the groundstate level of the hydrogen atom. Is this enough energy to ionise the atom? If so calculate the kinetic energy of the free electron.
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.
Consider these two cases. Case 1: An electron jumps from energy level 1 to energy level 2 in an atom. Case 2: An electron jumps from energy level 1 to energy level 3 in an atom. For case 1, what happens when an electron jumps from energy level 1 to energy level 2 in an atom? O A proton is emitted by the atom. O A photon is absorbed by the atom. O A photon is emitted by the atom....
In an atom, an electron jumps from an energy level of n = 5 to an energy level of n = 2. During this process, a photon was emitted by the atom. a photon was absorbed by the atom. a proton was emitted by the atom. a proton was absorbed by the atom. Now, compare the energy either emitted or absorbed by the atom in Scenario 1 to the energy emitted or absorbed in Scenario 2. An electron jumps from...
6) A photon of frequency f strikes and is absorbed by a stationary electron, after which the electron travels with velocity v in the same direction as the initial photon, and releases a photon of frequency f' in the opposite direction. Determine f and f' in terms of v and appropriate constants. f it Figure 6 w ę wkręty
