The energy of this photon is 3,7351.10e-19 joules.
The energy of the photon is 3,1631.e-19 joule.

Ultraviolet light is a form of radiation that is an invisible part of the electromagnetic spectrum. The energy of a photon of 320 nm ultraviolet light is 6.20764x10-19 Joules.
Energy of the photon = Planck's constant x frequency of the ultraviolet radiation E = h x f frequency of the ultraviolet radiation = speed of light / wavelength of the ultraviolet radiation f = c/ lambda E = 6.63 x 10-34 x 3 x 108 / 3 x 10-7 = 6.63 x 10-19 Joules
The energy is E=hf= hc/w = .2ppj/150nm=1.333e-18 joules.
3.84 x 10-19 joules.
IR: longer wavelength, lower frequency, lower energy per photon. Visible: medium wavelength, medium frequency, medium energy per photon. UV: shorter wavelength, higher frequency, higher energy per photon.
Both are electromagnetic radiation, and travel at the same speed in any given medium. But the wavelength of ultraviolet light is shorter than the wavelength of visible light, and each ultraviolet photon carries more energy than any visible photon.
Determine the energy and wavelength of a wave with a frequency of 3.6X 1016 hertz Would this be a wave of interest to nuclear medicine?
assuming the wave is electromagnetic... the energy of a single photon of that frequency is given by the formula E=hf where E= energy of the photon h=the Planck constant f= the frequency of the photon From this the energy of the photon is the Planck constant (6.63 x10-34) multiplied by the frequency 3.6x1016 Hz. E= 23.9x10-18 Joules. The wavelength of any wave is determined by the equation wave speed = frequency x wavelength. thus, the… Read More
Wavelength, frequency, and energy carried by each photon (light quantum).
The energy is E = hf=hc/r = .3636E-18 joules or 2.2727 electron volts.
for a photon energy= Planks Constant * frequency and frequency= speed of light/wavelength so E= hc/(wavelength) h= 6.63E-34 J/s c= 3E8 m/s Plug n' Chug
Ultraviolet radiation has a wavelength between 10 and 400 nanometers. The shorter the wavelength, the more energy each photon contains. To find the frequency, divide the speed of light (299,792,458 metets per second) by the wavelength.
You can use Plank's relation to calculate the energy of the absorbed photon. E = h.f = h.c/L given E = Energy of a photon in Joules f = frequency of the photon in s-1 c = speed of light in m/s L = wavelength of the photon in metre h = Planck constant = 6.62606957×10−34 J.s
No. A photon is not a unit of measurement. Ex. You cannot say: 1 Joule = 500 photons. Each photon varies in energy depending upon its wavelength.
The larger the wavelength of the photon, the lower the energy.
what is the energy of J of photon with a wavelength of 601nm?
The energy is hc/w = 2E-25/650E-9=307.692E-21 Joules = 1.923 electron volt.
Well, first of all, protons don't make light. I think you mean 'photons'. A photon of ultraviolet light carries more energy than a photon of visible light, because it has a higher frequency / shorter wavelength.
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.
Energy = hc/w= .2E-24/400E-9 = .5E-18 joules x 6.25E18 ev/J=3.125 ev.
Using velocity = frequency * wavelength, and noting that all Electromagnetic waves have a speed of 3.0 * 108 , the frequency of the light is 1.2 * 1015 Hz. The energy of a photon with a frequency, f, is given by Energy = fh; where h is the Planck's constant. Substituting values of f and h(= 6.26 * 10-34) , the energy of the photon is found to be 7.512 * 10-19 J.
Twice the energy means twice the frequency, and therefore half the wavelength.
The blue light has longer wavelength, lower frequency, and less energy per photon than the ultraviolet light has. The blue light is also visible to the human eyes, whereas the ultraviolet light is not.
Photon is electromagnetic radiation which comes from the sun. There are different types of light which include: visible, ultraviolet, and infrared. Photon energy is measured in wavelengths (nanometers- nm). The shorter the wavelength, the higher the energy. Visible light measures between 400 nm and 700 nm
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
The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely… Read More
Consider photons emitted from an ultraviolet lamp and a TV transmitter. Which is the greater wavelength Which is the greater momentum?
Good luck, Greater wavelength=TV. frequency= the number of wave cycles(peak, trough, peak) per time unit. The higher the frequency, the more times the wave cycles, and the shorter the wavelength. Greater Energy=Ultraviolet lamp. By Placks constant, E(energy) =h(planck's constant which is the energy of a photon divided by it's frequency) / f(the frequency of that photon). Planck's constant is almost irrelevant, so the greater the frequency, the greater the energy. Greater frequency=Ultraviolet lamp. Planck's constant… Read More
An electromagnetic wave with a longer wavelength will have a smaller frequency, and less energy per photon. An electromagnetic wave with a longer wavelength will have a smaller frequency, and less energy per photon. An electromagnetic wave with a longer wavelength will have a smaller frequency, and less energy per photon. An electromagnetic wave with a longer wavelength will have a smaller frequency, and less energy per photon.
The energy per photon is directly proportional to the frequency; the frequency is inversely proportional to the wavelength (since frequency x wavelength = speed of light, which is constant); thus, the energy per photon is inversely proportional to the wavelength.
It isn't. There is, however, a relationship between the wavelength, and the energy of an individual photon. The smaller, the wavelength, the larger will the frequency be - and therefore, also, the energy of a single photon.
Both are electromagnetic waves. The frequency of the different types of radiation varies, as does the energy per photon, and the wavelength.
The energy of a photon is directly proportional to the frequency. Since the frequency is inversely proportional to the wavelength, the energy, too, is inversely proportional to the wavelength.
What is the frequency in hertz and the energy in joules of an x-ray photon with a wavelength of 2.32 Å?
For the frequency, first convert the wavelength to meters (divide the number of Angstroms by 1010), then use the formula: wavelength x frequency = speed. Using the speed of light in this case. Solving for frequency: frequency = speed / wavelength. To get the photon's energy, multiply the frequency times Planck's constant, which is 6.63 x 10-34 (joules times seconds).
Yes. Energy is inversely proportional to wavelength. Shorter wavelength = more energetic.
The line spectrum of lithium has a red line at 670.8 calculate the energy of a photon with its wavelength?
2.93x10^-19 Joules first use the v=c/h formula to find frequency then use the energy formula to find energy.
The energy of a photon is directly proportional to the frequency. Since the frequency is equal to the speed of the wave (the speed of light) divided by the wavelength, it follows that the energy (of a photon) is inversely proportional to the wavelength.
The energy of a photon is directly proportional to its frequency. The frequency (and therefore also the energy) are inversely proportional to the wavelength (for any wave, frequency x wavelength = speed of the wave).
If the human eye can detect light with a radiant energy incident of at least 4x10 to the negative 17 Joules then for light of 600nm wavelength how many photons does this correspond to?
The energy E of a photon is E= h x f , where f is the frequency, and h is Planck's constant. h=6.63e-34 [aka 6.63 x 10^-34] J s (Joule-seconds) The frequency f of a photon is related to its wavelength by f=speed of light/wavelength Speed of light c=3e8 m/s. From this you can calculate the energy of a 600nm photon, and then the number of those photons required to get 4e-17 Joules. Your answer… Read More
From that list of choices, the ultraviolet photon is the most energetic.
Photon energy = (frequency) times (Planck's Konstant)
Microwave ovens emit microwave energy with a wavelength of 12.0 cm What is the energy of exactly one photon of this microwave radiation?
A photon of this wavelength has an energy of about 10 ^ -5 eV.
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
Energy of Photon = Planck's constant x speed of light / wavelength = 6.63 x 10-34 x 3 x 108 / 1050 x 10-9 = 1.89 x 10-19 Joules = 1.89 x 10-19 / 1.6 x 10-19 = 1.181 eV
The relationship between electromagnetic energy (photon energy) and wavelength is determined by two constants - the speed of light and Planck's constant. Photon energy (in Joules) is equal to the speed of light (in metres per second) multiplied by Plancks constant (in Joule-seconds) divided by the wavelength (in metres). E = hc/wavelength where: E is photon energy h is Planck's constant = 6.626 x 10-34 Js c is the speed of light = 2.998 x… Read More
The energy of a photon is described by the equation: Where l is the wavelength, h is Planck's constant, c is the speed of light, and E is the energy. So, the energy of a photon increases as the wavelength decreases.
