photoelectric effect

A particle of light is called a photon.

• True

• False

The energy of photoelectrons emitted from a metal surface can be increased by

• using monochromatic, polarized light.

• using light of longer wavelength.

• using light of higher frequency.

• using light of higher intensity.

This image is an illustration of:

• Dalton's atomic theory

• photoelectric effect

• Bohr model

• electron model

How could we get more energy into the red light?

• But the brightness (intensity) constant.

• Try decreasing the brightness (intensity).

• Try increasing the brightness (intensity).

Who won the Nobel Prize for this discovery?

• Albert Einstein

• John Dewey

• Elon Musk

• Jeff Bezos

If the photon has enough energy, Will the electrons get ejected or absorbed?
