In the photoelectric effect, increasing the intensity of light increases the:
  1. Kinetic energy of emitted electrons
  2. Number of emitted electrons
  3. Wavelength of emitted light
  4. Work function

Questions & Step-by-Step Solutions

In the photoelectric effect, increasing the intensity of light increases the:
  • Step 1: Understand that the photoelectric effect is when light hits a surface and causes electrons to be emitted.
  • Step 2: Know that light is made up of tiny particles called photons.
  • Step 3: Realize that intensity of light means how many photons are hitting the surface.
  • Step 4: When you increase the intensity of light, you are increasing the number of photons.
  • Step 5: More photons hitting the surface means more chances for electrons to be knocked out.
  • Step 6: Therefore, increasing the intensity of light increases the number of emitted electrons.
