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 related to its?
... frequency of the electromagnetic radiation of which the photon is a particle.
How can I calculate the energy of a photon if I know the wavelength?
Multiply (Planck's constant) times (the speed of light), and divide the result by the photon's wavelength.Be careful to keep the units consistent.
What is the energy of photon?
the energy of a photon is h times f
Describe the relationship between the wavelength and it's energy?
c is the speed of sound or the speed of light. You must know what you need. There is a relationship between the wavelength lambda and the frequency f. But forget the energy! c= lambda times f f is proportional to 1 / lambda. f = c / lambda lambda = c / f
How do you find wavelength if you've been given the energy?
The easiest way would be to find a descriptive article on the internet that shows the visible colors spread out with some wavelengths labeled. There, you can find the approximate wavelengths for light of various colors. If you don't know the color of the light, then in order to find its wavelength, you'd need to know either its frequency or the energy of a photon (quantum). Energy of a photon = h f h = Planck's Konstant = about 6.63 x 10-34 joule-second f = frequency of the light wave or photon But the frequency is (speed of light)/(wavelength) so, Energy = h c/wavelength . If you know either the energy of the photon or its frequency, you can use this stuff to find its wavelength. In this discussion, I've toggled back and forth a few times between the frequency/wavelength of the quantum and the frequency/wavelength of the light wave. Don't worry. They're the same.
How does the energy of three photons of blue light compare with that of one photon of blue light from the same source?
If the color (frequency, wavelength) of each is the same, then each photon carries the same amount of energy. Three of them carry three times the energy that one of them carries.

What is the energy of photon?
the energy of a photon is h times f
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).
That An electron requires 4 times 10-17 j of energy to be removed from it's atom what is the wavelength of a photon that has this much energy?
The wavelength is w = hc/E = .2E-24/4E-17 = 5E-9 meters.
If the inner accretion disk around a black hole has a temperature of 1000000 K at what wavelength will it radiate the most energy?
For a thermal radiation source, the peak of the blackbody radiation curve is at a photon energy 2.8 times the temperature in electron-volts. The temperature in electron-volts is 1/11,600 times the temperature in Kelvin. Use E = hv to convert from the photon energy (E) to photon frequency, using Plank's constant h. Use v = c/(lambda) to convert from the photon frequency to the wavelength. The result: these hot plasmas radiate X-rays, and the peak wavelength is about 50 Angstroms, i.e. 5 nm.

c is the speed of sound or the speed of light. You must know what you need. There is a relationship between the wavelength lambda and the frequency f. But forget the energy! c= lambda times f f is proportional to 1 / lambda. f = c / lambda lambda = c / f

How are engery and frquency of electromagnetic radiation related?
(The energy of each photon) is (the photon's frequency) times (Planck's Konstant). (The total energy in a beam of it) is (the energy of each photon) times (the number of photons in the beam).
How do you find energy when given frequency?
The energy of a photon of electromagnetic radiation is(Photon's frequency) times (Planck's Konstant) .
What is the wavelength in nm of a photon whose energy is 4.7 x 10-14 J?
First get the wavelength in meters by multiplying Plancks constant (in units of J-sec) times the speed of light (in m/sec) and divided by the energy. Then change to nanometers by multiplying by 1 billion.
