NON IMPULSIVE FORCE SKIN
Furthermore, the energy of UV photons is sufficient to ionize atoms or molecules in the skin, causing significant damage to individual skin cells. UV photons are thus more energetic than visible photons, and therefore, have the potential to inflict more damage to skin cells. In the photon model of light, the energy of a photon is determined solely by its frequency. This too makes sense as a result of the photon theory because each individual photon carries enough energy to cause a photoelectron to be emitted-only a single photon is required to start a photocurrent.
The final puzzling feature of the photoelectric effect was that electrons are emitted virtually instantaneously after turning on a photon source.
NON IMPULSIVE FORCE FREE
This is an understandable phenomenon because some minimum amount of energy is required to set the electrons free from the material to which they are bound, and if the photon energy is too low, an electron will not be ejected after absorption of a photon. The third puzzling feature was that for a given metal there is a threshold frequency below which no electrons will be emitted. This too is explained by the photon theory because a shorter wavelength photon has a greater energy, and therefore, will provide a larger " kick " to the photoelectron. The second puzzling feature was that the maximum kinetic energy of the electrons depends upon the wavelength of the photons. This is understood with the photon model of light because increasing the intensity of the radiation simply increases the number of photons colliding with the material but does not increase their energy. The first puzzling feature of this effect was that brighter light increases the current of electrons but does not affect their kinetic energy. The photoelectric effect describes the mechanism by which electrons are ejected from materials when certain frequencies of electromagnetic radiation are incident upon them. Thus, as the temperature of the bulb decreases, less high-frequency light is radiated and the emitted radiation becomes increasingly red. The frequency of maximum radiation output from a blackbody decreases as its temperature drops. The temperature of the filament drops as the bulb is dimmed.
