A scientist reproducing some photoelectric effect experiments shines a light on a metal electrode, but doesn't detect any current due to the light. One possible reason is:
| a. |
The light is not polarized |
|
| b. |
The light beam is not focused |
|
| c. |
The photons in the beam have energy less than the work function of the electrode |
|
| d. |
The light beam needs to be pulsed for the photoelectric effect to occur |
Homework Answers
there is no current means there is no flow of electrons ,there are no electrons means electrons are not ejected from the metal which means that the photons in the beam do not have enough energy to eject electrons from the metal option c is the right option

In the photoelectric effect experiment, a beam of light is shining on a metal surface and the electrons are emitted from the metal. One of the three key findings is that a minimum frequency of light is required for emission of electrons. This minimum frequency is found to be 5.5 × 1014 s-1 for an unknown metal. 4 Briefly describe the other two findings and draw a plot fo the KE of emitted electrons against light frequency.

A uniform ultraviolet light source shines on two metal plates causing electrons to be emitted from each plate. Plate A emits twice as many electrons as plate B. However, the electrons emitted from plate B have a higher maximum velocity. Which of the following describes a plausible explanation for the differences in electron emission? (Select two answers.) A) Plate A must have a larger work function than plate B. B) The higher velocity electrons in case B would be produced...
