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 is the wavelength of a photon that has Energy of 4 x 10 to the -17 power?
4.9695 nm
What is the SI measurement of light?
There is no "measurement of light". The units used depend on what you want to measure: its speed, frequency, wavelength, energy per photon, etc.
Why is a photon with a wavelength of 1050 multiplied by 10 to the negative 9th power?
Because the wavelength is not 1050 metres but 1050 nanometres.
Should it be possible for a photon to circle a star?
Yes, given the right conditions. Photons are affected by gravity.
What is the Mathematical relation between energy of radiation and wavelength?
The energy of a basic unit of electromagnetic energy, the photon, is related directly to its frequency by a scaling factor called Planck's Constant, and the equation is often written e = Hf where e is energy unit, H is Planck's Constant and f is frequency unit.
A photon of wavelength 3000 A is absorbed by a gas and remitted as two photons One of the photons is red 7600 A What is the wavelength of the other photon?
The total energy of a photon with a wavelength of 3000 A is divided into two photons, one red photon with a wavelength of 7600 A, and another photon with a shorter wavelength. To calculate the wavelength of the second photon, you can use the conservation of energy principle, where the sum of the energies of the two new photons is equal to the energy of the original photon. This will give you the wavelength of the other photon.
What is the no of photons of light with wave 4000 pm that provided 1J energy?
To calculate the number of photons, you can use the formula: Energy of 1 photon = hc / λ where h is Planck's constant, c is the speed of light, and λ is the wavelength. From this, you can determine the energy of one photon of light with a 4000 pm wavelength and then calculate the number of photons required to provide 1 Joule of energy.
What is the energy of 1 mol of blue photons at 400 nm wavelength?
The energy of a photon can be calculated using the equation E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength of the photon. Plugging in the values for h, c, and λ, we can calculate the energy of one photon at 400 nm. To find the energy of 1 mol of photons, we would multiply the energy of one photon by Avogadro's number.
If the detector is capturing 9 107 photons per second at this wavelength what is the total energy of the photons detected in one hour?
To calculate the total energy of the photons detected in one hour, first find the energy of each photon using E = hc/λ where h is Planck's constant, c is the speed of light, λ is the wavelength. Then convert the detected photons per second to per hour, and multiply by the energy per photon to get the total energy.
What you the no of photons of light with wave 4000 pm that provided 1J energy?
To calculate the number of photons that provide 1J of energy for light with a wavelength of 4000 pm, we need to use the formula E=nhf, where E is the energy, n is the number of photons, h is the Planck's constant, and f is the frequency. First, calculate the frequency using the speed of light formula, c=λf. Then, calculate the energy per photon using E=hf. Finally, divide the total energy by the energy per photon to find the number of photons.
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.
The energy of a photon depends on what?
The energy of a photon depends on its frequency or wavelength. The energy is directly proportional to the frequency of the photon, meaning that higher frequency photons have higher energy levels.
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 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 are the wavelenght and energy of a photon related?
The wavelength and energy of a photon are inversely related: shorter wavelengths correspond to higher energy photons, while longer wavelengths correspond to lower energy photons. This relationship is 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.
How do you calculate photon flux given v?
Photon flux can be calculated using the formula: photon flux = v * E, where v is the frequency of the photons and E is the energy of each photon. By multiplying the frequency of the photons by the energy of each photon, you can determine the photon flux.
How do you calculate energy per mole of photons if you know joules per photon?
To calculate the energy per mole of photons from the energy per photon, you need to multiply the energy per photon by Avogadro's number (6.022 x 10^23) to account for the number of photons in a mole. The formula is: Energy per mole of photons = Energy per photon x Avogadro's number.
