A particular sensitizer can absorb photons of one wavelength and release photons of a longer wavelength Why must the radiation be at a longer wavelength?
First, consider the relationship between wavelength and energy and reformulate the premise in terms of energy. Then, study fluorescence, the process in which a molecule absorbs a photon and releases a subsequent photon at a longer wavelength. In fluorescence, energy must be conserved. The total energy absorbed must be equal to the total energy released by the excited molecule (sensitizer). The question is asking, for example, if a sensitizer absorbs a photon with energy of 3 eV and releases a photon of 2.5 eV, where did the missing 0.5 eV go? This question comes directly from the laboratory manual for the introductory chemistry courses at the University of Alabama. For those students attempting to find an easy answer without putting forth any effort, i.e. cheat, you'll have to look elsewhere. - Mr. E.
What is the wavelength of the photon that has been released in Part B?
The wavelength of a photon can be calculated using the equation: wavelength = Planck's constant / photon energy. Given the photon energy, you can plug in the values to find the corresponding wavelength.
What is the relationship between wavelength of light and the energy of its protons?
The energy in one photon of any electromagnetic radiation is directly proportionalto its frequency, so that would be inversely proportional to its wavelength.Note: There is no energy in the protons of light, since light has no protons.
How do you calculate the number of photons that corresponds to 600 nm of light?
λ - wavelength (NM) c - speed of light (3x108 m/s)= 162 000 nmf - Frequency (Hz)λ = c \ f600=162 000 nm\ f f=270 Hz
When an electron in atom changes energy states a photon is emitted If the photon has a wavelength of 550 nm how did the energy of the electron change?
The energy of the electron decreased as it moved to a lower energy state, emitting a photon with a wavelength of 550 nm. This decrease in energy corresponds to the difference in energy levels between the initial and final states of the electron transition. The energy of the photon is inversely proportional to its wavelength, so a longer wavelength photon corresponds to lower energy.
What is the longest wavelength photon?
There is no longest wavelength for photons. It can be arbitrarily long.
When matter absorbs a photon what is the relationship between the energy of the matter before and after the absorpion and the frequency and the wavelength of the radiation absorbed?
When matter absorbs a photon, the energy of the matter increases by an amount equal to the energy of the absorbed photon. The frequency and wavelength of the absorbed radiation depend on the energy of the photon and are inversely related - higher energy photons have higher frequencies and shorter wavelengths.
How do you calculate photon wavelength with only the energy of the photons?
Photon Energy E=hf = hc/w thus wavelength w= hc/E or the wavelength is hc divided by the energy of the photon or w= .2 e-24 Joule meter/Photon Energy.
What determines which photon an atom can absorb or emit?
An atom can absorb or emit photons based on its energy levels and electronic structure. When a photon energy matches the energy difference between two energy levels in the atom, it can be absorbed or emitted. This is governed by the quantized nature of energy levels in atoms.
How are photons absorbed by materials and what happens to them afterwards?
Photons are absorbed by materials when their energy matches the energy levels of electrons in the material. When a photon is absorbed, it can cause an electron to move to a higher energy level or be released as heat. The absorbed energy can also be re-emitted as a new photon or used to create a chemical reaction.
How are color wavelength and photon energy related?
Color wavelength and photon energy are inversely related. This means that as the wavelength of light decreases and the frequency increases, the energy of the photons also increases. Shorter wavelengths correspond to higher energy photons, such as in the case of ultraviolet light having higher energy than visible light.
Does a photon have a de Broglie wavelength?
Yes, a photon does have a de Broglie wavelength, which is given by λ = h/p, where h is Planck's constant and p is the photon's momentum. Photons exhibit both wave-like and particle-like properties.
What is the amount of energy for each photon called?
It depends on the wavelength of the photon. Energy of each photon is hc/λ, where h = Planck's constant = 6.626x1034 Js, c = speed of light = 3x108 m/s, and λ = wavelength of the photon
How are the wavelength and energy of a photon related?
The energy of a photon is inversely proportional to its wavelength. This means that shorter wavelengths have higher energy photons, while longer wavelengths have lower energy photons. Mathematically, the relationship can be described by the equation E=hc/λ, where E is energy, h is Planck's constant, c is the speed of light, and λ is the wavelength.
The energy of a photon depends on what?
The energy of a photon depends on it's frequency
The measure of a photon's energy?
The energy of a photon is determined by its frequency or wavelength, following the equation E = hf, where E is energy, h is Planck's constant, and f is frequency. Photons with higher frequencies have more energy.
How to Put these photons in order of increasing energy?
To arrange photons in order of increasing energy, you can use 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. Photons with higher frequency will have higher energy. So, simply compare the frequencies of the photons to determine their energy order.
