A PMT contains 11 dynodes. If 1 photon strikes the photocathode, how many electrons reach the anode? Record your answer to the 1s place.

The rate at which solar wind particles enter the atmosphere is higher during the day than at night, yet the intensity of the auroral emissions remains high well after the Sun has set. Can you suggest a means by which the atmospheric molecules might be able to radiate long after the period of collisions with charged particles has ended? (Hint: How long does it take a typical atom to radiate from a normal allowed energy state? How could this time be lengthened?)

If a photon has energy of 4.3 eV, calculate its' wavelength. Report your answer in nm . Your Answer: Answer

The energy of a “red” photon emitted from a HeNe LASER is 3.134x10-19 J. Calculate the total energy if (a) 1 doz photons came out of the LASER and (b) 1.00 mol of photons came out.       Please type answer note write by hend.

how would you answer this? The maximum kinetic energy of photoelectrons is plotted as a function of the frequency of incident light. The slope of this graph is.. would appreciate work shown for this question, thanks   a Planck’s constant. b Rydberg’s constant. c Coulomb’s constant. d Newton’s gravitational constant.

This is one question with 3 parts so it is not against guidelines to answer all 3 parts. Please use simplistic terminology for the answers doesn’t have to to be long. Your are looking at 27-29

help please

The work function of a certain metal is found to be 1.82 eV. What is the stopping potential required to to stop the current in a photoelectric effect experiment if the wavelength of the incident light is 413 nm. Round your answer to 3 significant figures. Add your answer

Within what lower limit could we determine the position of each object along the direction of the velocity?

(Give the lower limit for the electron in nm and that for the bullet in m.) for the electron Again, you will need to use the uncertainty principle, but note now the velooty is high compared to the speed of fight. So, you will need to use the relativistic definition of momentum. To find the uncertainty in velocity, treat the momentum and velocity…
