How does the frequency of light affect the release of electrons?
As the frequency increases beyond the threshold, the ejected electrons simply move faster. An increase in the intensity of incoming light that is above the threshold frequency causes the number of electrons that are ejected to increase, but they do not travel any faster.
What causes different frequencies of light to be emitted by different elements?
Explanation: When atoms are heated, electrons will move from their ground state (lower energy level) to a higher energy level. This process is called excitation. The photons will have different wavelengths and frequencies, this makes photons of different energies produce different colors of light.
What determines the frequency of the emitted light?
Frequency. The wavelengths and frequencies of the light emitted by an atom (its emission spectrum) is determined by its electronic structure. In the Bohr model shown above you can see that as each electron moves from a higher energy level (orbit) to a lower one, a different color is emitted.
Why do different atoms emit different wavelengths of light?
Explanation: The electrons in an atom can only occupy certain allowed energy levels. Only certain energy levels are allowed, so only certain transitions are possible and hence specific wavelengths are emitted when an electron drops to a lower energy level.
Will higher frequency light eject greater number of electrons than low frequency light?
High frequency light won’t necessarily eject a greater number of electrons from the photosensitive surface as the number of ejected electrons is often proportional to the number of incident photoelectrons. It is also affected by the brightness of the light. Frequency doesn’t have any effect.
How does the frequency of light affect the release of photons?
The higher the frequency, the more energy the photon has. Of course, a beam of light has many photons. This means that really intense red light (lots of photons, with slightly lower energy) can carry more power to a given area than less intense blue light (fewer photons with higher energy).
What frequency of light is emitted by electrons?
For example, when an electron falls from the third energy level to the second energy level, it emits a photon of red light (wavelength of about 700 nm 700\text { nm} 700 nm700, start text, space, n, m, end text); however, when an electron falls from the sixth energy level to the second energy level (larger transition).
Why do electrons emit light?
The color of light that is emitted by an atom depends on how much energy the electron releases as it moves down different energy levels. When the electrons return to lower energy levels, they release extra energy and that can be in the form of light causing the emission of light.
Does higher frequency light eject more electrons?
Originally Answered: Will higher frequency light eject the greater number of electrons than low frequency light? Yes, light with higher frequency, such as UV light carries more energy than lower frequency light (infrared), therefore is more capable of knocking electrons out of a material.
