What is a quantum of electromagnetic energy called?
. . . photon.
What happens when electrons in conduction band loses its energy and falls to a hole in the valence band?
The energy leaves as either a photon or phonon.
Can the neon in a glass tube be excited more than once?
Yes, the gas is ionized every time sufficient voltage is applied and remains that way until the voltage is removed. While the gas is ionized, individual neon atoms are continually bombarded by free electrons, causing their orbital electrons to jump to higher energy (excited) states. When an electron falls back to the lower energy state, it emits a photon.
What is a photovoltaic device?
A photovoltaic device is a device that absorbs light (infrared, visible, and ultraviolet) and produces an electric potential. Photovoltaic devices operate by using the energy from an absorbed photon to excite an electron (or hole) across a p-n junction. While longer wavelengths (microwaves) and shorter wavelengths (X-rays) of electromagnetic energy can also be used to produce electric potentials, the devices that do this are not considered photovoltaic because they operate on different principles.
Single oscillator energy Eo?
Optical properties of solids are described by the wavelength dependence of the complex refractive index. This is how the medium (the solid) responds to the electromagnetic wave. The dispersion of the real refractive index n(E), where E is the photon energy can be described with the model of many oscillators (electrons), which react to the electromagnetic wave. Simplifying the relations we obtain an equation of a single oscillator with effective parameters, which reflect the contributions of all the oscillators. These parameters are the oscillator strength Ed and the oscillator energy E0. So the oscillator energy is a parameter, connected with the optical properties of the solid and the electron transitions - it is connected with the optical bandgap Eg with the relation E0~1.5Eg.
Can you explain why an electron's energy increases when it absorbs a photon and also describe what happens to the photon in this process?
When an electron absorbs a photon, its energy increases because the photon transfers its energy to the electron. The photon ceases to exist as a discrete particle and its energy is absorbed by the electron, causing it to move to a higher energy level.
Which equation was used by Albert Einstein to explain the photoelectric effect?
Einstein used the equation E = hf to explain the photoelectric effect, where E is the energy of a photon, h is Planck's constant, and f is the frequency of the light. This equation shows that the energy of a photon is directly proportional to its frequency.
How does photon energy change with wavelength?
The energy of a photon is inversely proportional to its wavelength. This means that as the wavelength increases, the energy of the photon decreases. Conversely, as the wavelength decreases, the energy of the photon increases.
The light bearing packet of energy emitted by an electron is called a?
A packet of light energy is called a photon.
What type of energy does a photon in a quantum have?
A photon in a quantum has electromagnetic energy.
The energy of a photon depends on what?
The energy of a photon depends on it's frequency
How does the energy of a photon compare in difference in energy levels of the atom from which it is emitted?
The energy of a photon emitted from an atom is determined by the energy difference between the initial and final energy levels of the atom. The energy of the photon is directly proportional to this difference in energy levels. If the energy levels are farther apart, the emitted photon will have higher energy, whereas if the levels are closer together, the photon will have lower energy.
What is the relationship between photon frequency and the energy of a photon?
The relationship between photon frequency and energy is direct and proportional. As the frequency of a photon increases, its energy also increases. This relationship is described by the equation E hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency of the photon.
What is the wavelength of a photon whose energy is twice that of a photon with a 580 nm wavelength?
Since the energy of a photon is inversely proportional to its wavelength, for a photon with double the energy of a 580 nm photon, its wavelength would be half that of the 580 nm photon. Therefore, the wavelength of the photon with twice the energy would be 290 nm.
How is the wavenumber related to the energy of a photon?
The wavenumber of a photon is inversely proportional to its energy. This means that as the wavenumber increases, the energy of the photon decreases, and vice versa.
A packet of energy that carries a quantum of energy?
A photon is a packet of energy that carries a quantum of energy. It is an elementary particle that is the quantum of the electromagnetic field, including electromagnetic radiation such as light. The energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength.
Which is the relationship between photon energy and frequency?
Photon energy is directly proportional to frequency. This relationship is described by the equation E = hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency of the photon. This means that as frequency increases, photon energy also increases.
