A photon emitted by an excited atom has an energy of 2.5 eV. What is its frequency?
(a) What energy (in eV) would a photon have, if it were emitted when an electron dropped from the n = 5 level to n = 2? 2.865 eV (b) The equation for a photon's energy can be written: Echo where h is known as Planck's constant and is equal to 4.136 x 10-15 eV · s. (Note that h has a different numerical value in SI units.) Since we know that for light © = f, we can rewrite...
4. A photon is emitted as a result of an electron transition from a higher energy level to a lower energy level. Indicate the type of a photon that is emitted if its energy is equal to (a) 2.49 eV and (b) 1.38 eV. (Hint: Solve for the wavelength and usc table 21 in the cosc nosto deicm mine the type of photon.)
A γ ray photon emitted by 22688Ra has an energy of 0.186 MeV. Use conservation of linear momentum to calculate the recoil speed of a 22688Ra nucleus after such a γ ray is emitted. Assume that the nucleus is at rest initially, and that relativistic effects can be ignored. v= m/s
4. A photon is emitted when a hydrogen atom undergoes a transition from the n = 5 state to the n = 3 state. a. Calculate the wavelength of the emitted photon. b. What is the energy in eV of the emitted photon?
Calculate the average photon energy of the radiation emitted from the sun (e.g. a 5780K blackbody radiator). Calculate the average photon energy emitted from earth (e.g. a 300K blackbody radiator). Provide each answer in eV.
In order for an electron to be emitted, the energy of the incoming photon must be greater than the work function of the metal. A work function tells us the minimum energy an electron needs to gain in order to escape the material in which it is embedded. A gold cathode plate has a work function of 5.1 eV. If there is a voltage of 3.5 V applied across the plates, with the electrons ejected from the positive plate, what...
