What does nm in calculation of ultraviolet rays mean?
nm = nanometers It is a measure of the wavelength of the light, with energy inversely proportional to the wavelength: E = h / wavelength
Transition A produces light with a wavelength of 400 nm Transition B involves twice as much energy as A What wavelenth light does it produce?
Energy per photon is proportional to frequency. That tells us that it's alsoinversely proportional to wavelength.So if Photon-A has wavelength of 400-nm, then wavelength of Photon-Bwith twice as much energy is 200-nm .
Energy of the red light emitted by a neon atoms with a wavelength of 703.2 nm?

What is the energy of a photon emitted with wavelength of 518 nm?
3.84 x 10-19 joules.
How do you calculate the energy in joules of a photon of green light having a wavelength of 529 nm?
The energy of this photon is 3,7351.10e-19 joules.
Why cant light of 500 nm be given off from hydrogen?
Hydrogen, like all elements, have a characteristic distance between energy levels. The atom can only accept photons of energy that match that distance and then that light is emitted. 500 nm does not match the wavelength of light that matches the wavelength corresponding to the energy gap in hydrogen.
What is the wavelength of a photon with an energy of 4.56 J?
The wavelength is 436 nm.
What does nm in calculation of ultraviolet rays mean?

What is the energy of a 500 nm photon?
The energy of a 500 nm photon is 3.1 eV (electron volts). This is a unit of measure used to represent the energy of a single photon. To put this into perspective, a single photon of visible light has an energy of 1.8 to 3.1 eV, and a single photon of ultraviolet light has an energy of 3.1 to 124 eV. The energy of a 500 nm photon can be calculated by using the following equation: E = hc/ Where: E = energy of the photon (in eV) h = Planck's constant (6.626 * 10-34 Js) c = speed of light (2.998 * 108 m/s) = wavelength of photon (in meters) Therefore, the energy of a 500 nm photon is calculated as follows: Convert the wavelength from nanometers to meters: 500 nm = 0.0005 m Insert the values into the equation: E = (6.626 * 10-34 Js) * (2.998 * 108 m/s) / (0.0005 m) Calculate the energy: E = 3.1 eVTherefore, the energy of a 500 nm photon is 3.1 eV.
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
What is the wavelength of a photon with an energy of 3.26 10 19 J?
The wavelength is 610 nm.
What is the energy of light with a wavelength of 595 nm?
Yes, that seems to be more or less the correct wavelength for blue light.

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.
