Photoelectric Emission
 

Photoelectric Emission problem 13


A metal plate is illuminated with some light. We want the speed of the ejected electrons to be as high as possible. What we can do to achieve the desired goal?

  • We shorten the distance between the light source and the surface of the metal.

  • We reduce the wavelength of the light.

  • We increase the brightness of the source.

  • We increase the angle of incidence of the light on the metal.

  • We increase the frequency of the light.

  • We increase the power of the light source.

  • We reduce the angle of incidence of the light on the metal.

  • We increase the wavelength of the light.
