E = hf, where E is energy in Joules, h is Planck's constant, 6.626 x 10-34 J•s, and f is frequency in /s or Hz.
E = (6.626 x 10-34J•s)(8 x 1012 Hz) = 5 x 10-21J
5.3 x 10 ^ -21 J
The energy in the beam depends on whatever source is generating it.
We can calculate the energy in each photon of that electromagnetic wave,
but that doesn't tell us how many photons are pouring out of the source.
The energy in each photon is (Planck's Konstant) x (Frequency)
Planck's Konstant = 6.63 x 10-34 joule-sec
Energy in each photon = (6.63 x 10-34 joule-sec) x (3,109 per second) = 2.061 x 10-30 joule
If the source produces 1 trillion trillion of those every second, then the power
pouring out of the source is 0.000002061 watt.
A blinding beam, to be sure. But I'm not worried, because I happen to know that
in order to radiate electromagnetic energy with reasonable efficiency, you'll need
a dipole antenna that's 1/2 wavelength long, and with my innate knack for figures,
I quickly realize that at 3,109 Hz, a half-wavelength is 96 Km (59.92 miles), so it's
doubtful that you'll be on the air and radiating with that puppy for some time.
f = E/h, where f is frequency, E is energy, and h is Planck's constant, 6.626 × 10-34 J.s.
If frequency is known, you can find E by manipulating the equation such that E = f x h = (3 x 109Hz)(6.626 × 10-34 J.s) = 2 x 10-24J.

In nuclear reactions, energy is usually released. This energy is released as an electromagnetic wave. Because of the large amount of energy involved, this wave has a high frequency/energy - a gamma ray.
A gamma ray is an electromagnetic wave. It has the highest frequency (and energy) as well as the shortest wavelength on any wave on the electromagnetic spectrum.
For any point on the electromagnetic spectrum, the product of(wavelength) multiplied by (frequency) is 299,792,458 meters per second.That's the speed of the wave.
It is generally unrelated.In the case of an electromagnetic wave, the energy FOR A SINGLE PHOTON is directly proportional to the frequency, i.e., at higher frequencies the photons have more energy. But that tells us nothing about the energy of larger amounts of light, for example.
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 wavelength is the wave speed divided by the frequency. since all electromagnetic waves travel at the speed of light then... wavelength = 3x108 / 3.6x1016 wavelength = 0.83x10-8 = 8.3x10-9 metres. The electromagnetic radiation corresponding to this energy and wavelength is ultraviolet radiation and may be of interest to nuclear medicine.

There is no upper limit to how much energy (and frequency) an electromagnetic wave can have. The highest frequency waves are called gamma radiation.There is no upper limit to how much energy (and frequency) an electromagnetic wave can have.

The lower the frequency is, the less energy the electromagnetic wave carries. The wavelength is just (186,282 divided by the frequency) miles, or (300,000 divided by the frequency) kilometers.
Frequency determines the scalar energy of electromagnetic wave, E= hf=hc/r.

Depends on the wave. In electromagnetic waves, a shorter wavelength means a higher frequency - and the energy of a photon is directly proportional to frequency.
En electromagnetic wave is assimilable to a photon. The energy of a photon is equal to its frequency (that determines its "color") multiplied by the Planck's constant (h).
Yes, energy transfer for mechanical waves is dependant on frequency as well as amplitude. Energy of electromagnetic waves, however, does not rely on frequency but solely on amplitude.
