The energy of each photon at that frequency is ... (Planck's Konstant) x (frequency) =
(6.63 x 10-34) x (8 x 1012) =
5.304 x 10-21 joule
The total energy in a wave packet at that frequency is (that number) times the
total number of photons radiated from the source. The more energy you want to
radiate, the brighter source you use, and the longer you keep it turned on.

What is the infrared portion of the electromagnetic spectrum?
The Infrared is roughly from 1 Terahertz to 400 Terahertz, 1012 to 400 1012 .
What is the wavelength that corresponds to a frequency of 6.00 x 10-14 Hz?
Frequency = 6.00 x 10-14 Hz Wavelength = (speed) /(frequency) -- If this wave is sound in air, then the speed is 343 m/s and the wavelength is 5.72 x 1012 kilometers. -- If this is an electromagnetic wave in vacuum, then the speed is 299,792,458 m/s and the wavelength is 5 x 1018 kilometers.
What is the frequency of infrared light?
1 x 1012 - 4.3 x 1014 Hz the frequency is 300 to 400 thz (tera hertz). the wave length is 1mm to .0008mm
What is the electro magnetic spectrum?
Electrical charges in motion produce emission of electromagnetic waves, like radio waves we use for cell phones and radio programs, millimeter waves we use in radars, visible light, X-rays and gamma rays. All the above forms of electromagnetic radiation differs from their frequency, in particular I have listed them in order of increasing frequency (and decreasing wavelength). When a real wave is emitted a set of frequencies are emitted, almost never a single frequency. Under a fundamental point of view this is due to the quantum mechanical indetermination principle. In practical cases, quite more important causes are the fluctuations in the speed of moving charges and the fact that their trajectory is not purely linear. The set of frequencies that forms a practical wave is called electromagnetic spectrum of that wave. The overall frequency axes is divided in zone, as listed below Region Wavelength (Angstroms) Wavelength (centimeters) Frequency (Hz) Energy (eV) Radio > 109 > 10 < 3 x 109 < 10-5 Microwave 109 - 106 10 - 0.01 3 x 109 - 3 x 1012 10-5 - 0.01 Infrared 106 - 7000 0.01 - 7 x 10-5 3 x 1012 - 4.3 x 1014 0.01 - 2 Visible 7000 - 4000 7 x 10-5 - 4 x 10-5 4.3 x 1014 - 7.5 x 1014 2 - 3 Ultraviolet 4000 - 10 4 x 10-5 - 10-7 7.5 x 1014 - 3 x 1017 3 - 103 X-Rays 10 - 0.1 10-7 - 10-9 3 x 1017 - 3 x 1019 103 - 105 Gamma Rays < 0.1 < 10-9 > 3 x 1019 > 105 Sub-zones are also defined. Since the energy of a photon of an electromagnetic wave at a certain frequency f is proportional to the frequency by the equation Energy= h f where h is the Plank constant, higher the frequency, higher the phonons energy as indicated in the table (the energy of one electronvolt eV is the energy aquired by an electron when accelerated by a potential of one volt and it is equal to 1.6×10−19 joule).
What does the frequency of light determine?
It can determine a lot of different things. You can determine the wavelength of the light wave from the frequency and the speed: wavelength = (speed)/(frequency). Speed of light is approximately 3 x 108 m/s. The energy of the photons can be determined by the frequency: Energy of a photon = h * frequency; h is Planck's constant = 6.626 x 10-34 Joule*sec. Higher frequency waves are sometimes called high-energy waves (X-rays, gamma rays for example) Different frequencies of visible light will be different colors. Red has the lowest frequency of the visible spectrum, and violet is the highest frequency. Note that each color is not a specific frequency, but a range of frequencies, with the color shifting as frequency gradually changes. Red: 400 to 484 THz (TeraHertz or 1012 Hertz) Orange: 484 to 508 THz Yellow: 508 to 526 THz Green: 526 to 606 THz Cyan: 606 to 630 THz Blue: 631 to 668 THz Violet: 668 to 789 THz See Related Links (Wikipedia & Wolfram ScienceWorld)
What is the energy of an electromagnetic wave with a frequency of 8 x 1012?
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
Wave length of electromagnetic radiation having a frequency of 5.00 x 1012?
Divide the speed of light (300 x 106 meter/second) by the frequency. The answer will be in meters.

What is the percent of 1012?
percent of 1012 = 101200%= 1012 * 100%= 101200%
Which is false statement for EM spectrum - Most is visible light - less than a nanometer to verakilometer - lowest frequencies have least energy?
"Most is visible light" is false. Visible light is but a small part of the electromagnetic spectrum. Also, "vera" is not a valid SI prefix. Perhaps you mean "tera", which is 1012.
