What is the energy of a photon emitted with wavelength of 518 nm?
3.84 x 10-19 joules.
What is the energy of a photon emitted with a wave length of 654 nm?
The energy of a photon can be calculated using the equation E = hc/λ, where E is the energy of the photon, h is Planck's constant (6.626 x 10^-34 J*s), c is the speed of light (3.0 x 10^8 m/s), and λ is the wavelength of the photon. Plugging in the values, the energy of a photon emitted with a wavelength of 654 nm (or 6.54 x 10^-7 m) is approximately 3.02 x 10^-19 J.
The light bearing packet of energy emitted by an electron is called a?
A packet of light energy is called a photon.
When an electron drops from a higher energy state to a lower energy state?
A photon is emitted when an electron falls from a higher to lower orbital. A photon is an elementary particles, the quantum of light and all other forms of electromagnetic radiation.
Why there are discontinous spaces between spectrum of hydrogen?
There are spaces in the atomic spectrum of hydrogen because there are discrete energy levels that the electron in the hydrogen atom can be located in. Generally speaking the further away from the nucleus, the higher the potential energy of the electron. When hydrogen gas is excited, the electron can jump up to higher energy levels. When that electron falls back down to a lower energy level, a photon is emitted with an energy equal to the energy difference between the atomic orbital it jumped from and the one it jumped to. Since excited electrons can make a number of different jumps (ex. 4->3, 4->2, 5->3, 5->2, etc) there are a series of photons given off with discrete energies. Each one of these photons has a distinct wavelength (given 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). Each line you see on the spectrum is a photon produced from a different energy jump, with a different wavelength. We are only able to see the photons that emit a wavelength in the visible spectrum (roughly 400-700 nm).
What is the energy of a photon emitted with a wavelength of NM?
4.44 10-19 j
What is the energy of a photon emitted with wavelength of 518 nm?
3.84 x 10-19 joules.
What is the energy of a photon emitted with a wavelength of 92.323 nm?
The energy is 2,5116.10-18 J or 13,429 eV.
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?
electron lost 3.6 x 10-19 -barbie=]
When an electron falls from a higher energy level to a lower energy energy level how is the energy released?
The energy is released as electromagetic energy and each transition in each atom has its own wavelength for the light emitted.
How do you find the energy of a photon?
You need to know the photon's frequency or wavelength. If you know the wavelength, divide the speed of light by the photon's wavelength to find the frequency. Once you have the photon's frequency, multiply that by Planck's Konstant. The product is the photon's energy.
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 is the wavelength of a photon whose energy is twice that of a photon with a 580 nm wavelength?
Twice the energy means twice the frequency, and therefore half the wavelength.
What is the energy of a photon emitted with a wave length of 654 nm?
The energy of a photon can be calculated using the equation E = hc/λ, where E is the energy of the photon, h is Planck's constant (6.626 x 10^-34 J*s), c is the speed of light (3.0 x 10^8 m/s), and λ is the wavelength of the photon. Plugging in the values, the energy of a photon emitted with a wavelength of 654 nm (or 6.54 x 10^-7 m) is approximately 3.02 x 10^-19 J.
The measure of a photon's energy?
wavelength
The light bearing packet of energy emitted by an electron is called a?
A packet of light energy is called a photon.
What is the wavelength of a photon that has three times as much energy as that of a photon whose wavelength is 779 nm?
Photon energy is proportional to frequency ==> inversely proportional to wavelength.3 times the energy ==> 1/3 times the wavelength = 779/3 = 2592/3 nm
