The speed of the electrons ejected from a metal surface can be increased by
using light of higher frequency.
using light of longer wavelength.
using light of higher intensity.
using monochromatic, polarized light.
The energy of a photon is directly proportional to its _____ and inversely proportional to its ______.
intensity - speed
wavelength - frequency
frequency - wavelength
intensity - wavelength
Light of a single wavelength is incident on a metal. Electrons are released. The intensity of the light is then increased while keeping frequency constant.
