Since the wavelength times the frequency is equal to the speed of the wave, all you need to do in this case is divide the speed of light (in meters/second) by the frequency. The answer will be in meters.
For calculating the energy, use E=h x f
where
E= energy of the radiation,
h=Planck's constant=6.626 x 10-34
and f=frequency of radiation
E=6.626 x 10-34 x 4.6 x 1014 =28.4918 x 1020 Joules
Wavelength = speed/frequency
In vacuum, wavelength = 299,792,458/4.72 x 1014 = 635.15 nanometers
(Red light, not much shorter than the limit of visibility for the human eye.)
I'll give you the equation to figure it out. E=hf, where h is Planck's constant, and f is the frequency.
Wavelength = (speed of light) / (frequency) = (3 x 108 / 4.56 x 1014) = (3 / 4.56) x 10-6 = 6.579 x 10-7 meter(rounded)
4.56e14 Hz = 6.5744e-7 meters wavelength
The energy is 2,9685.10e-19 joule.
635 nm (ap3x)
The energy is 3,6112.10e-19 joule.
Yes. The energy is given by plank's constant times the frequencie of the photon (remember that light is both particle and wave). So since blue light has higher frequency than green light, it is more energetic.
The energy in one photon of any electromagnetic radiation is directly proportionalto its frequency, so that would be inversely proportional to its wavelength.Note: There is no energy in the protons of light, since light has no protons.
A photon is a theoretical particle of light.The energy of a photon is directly proportional to the frequency of the light.E = hνwhere E = energy of the photonh = Planck's constant = 6.63 × 10-34 m2 kg s-1ν = frequency of the lightNote: ν in the equation above is not the English letter 'v' but the Greek letter 'nu' (pronounced new).

Wikipedia says that a photon is a fixed quantity of light energy.
The amount of energy in a photon of light is proportional to the frequency of the corresponding light wave.... frequency of the electromagnetic radiation of which the photon is a particle.
The energy is 3,8431.10e-14 joule.
If the photon is having very less frequency (say v=1Hz) ,then the Energy of such photon will be the smallest one. It can be inferred that the smallest unit of light energy will correspond to the smallest frequency of such quanta. But from the uncertainty principle it limits the energy of a quanta.
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 proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.
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.
A particle of light. Or, in general, of an electromagnetic wave.
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.
Wavelength, Frequency, or Photon Energy
A photon is a massless particle, meaning it has no rest mass. Its mass is zero, but it does have energy and momentum.
Visible light has a higher frequency, a higher energy per photon, and a smaller wavelength, compared to infrared.
The energy increases as the frequency increases.The frequency decreases as the wavelength increases.So, the energy decreases as the wavelength increases.
... frequency of the electromagnetic radiation of which the photon is a particle.
