What does the frequency of an emitted photon depend on?
A photon is a particle of light which essentially is a packet of electromagnetic radiation. The energy of the photon depends on its frequency (how fast the electric field and magnetic field wiggle, this needs better wording, for ‘fast electric field’ and ‘wiggle’). The speed of light (c) in a vacuum is constant. …
What affects the frequency of a photon?
The amount of energy is directly proportional to the photon’s electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon’s frequency, the higher its energy. Equivalently, the longer the photon’s wavelength, the lower its energy.
What happens if the frequency of a photon increases?
An increase in frequency produces a proportional decrease in the wavelength of light with a corresponding increase in the energy of the photons that make up the light. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa.
What happens to frequency when the wavelength of a photon increases?
As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer. There are two basic types of waves: mechanical and electromagnetic.
Is frequency the number of photons emitted?
According to the equation E=n⋅h⋅ν (energy = number of photons times Planck’s constant times the frequency), if you divide the energy by Planck’s constant, you should get photons per second.
Why does the frequency increase and the wavelength decrease?
When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same.
What is the relationship between frequency and wavelength?
Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength. For this reason, the wavelength ratio is the inverse of the frequency ratio.
How do you find the number of photon emitted?
