Which of the following was not a result of the photoelectric effect?

The maximum energy of the emitted electrons increases as the light's frequency increases

Electrons are emitted for all frequencies of light

The maximum energy of the emitted electrons is independent of the light's intensity

The emission of electrons happens almost instantaneously even at low intensities of light.

Answer #1

the equation of photoelectric effect is:-

hf = \phi + E_k

the elcetron will only emit when it crosses the value of \phi , so electrons wont be emitte for all the frequency of light.

Electrons are emitted for all the frequency of light is not a result of the photoelectric effect

  • The photoelectric effect

    Electrons are emitted from the surface of a metal when it's exposed to light. This is called the photoelectric effect. Each metal has a certain threshold frequency oflight, below which nothing happens. Right at this threshold frequency, an electron is emitted. Above this frequency, the electron is emitted and the extra energy istransferred to the electron.The equation for this phenomenon is KE=hv-hv0 where KE is the kinetic energy of the emitted electron, h=6.63x10^-34 J.s is Planck's constant, v is the...

    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.
