What is the energy of a photon of light having a wavelength of 4.5 x 10-7 meters (Planck and rsquos constant is 6.626 x 10-34 joule seconds the speed of light is 2.998 x 108 ms)?

-- The frequency of that light is speed/wavelength = 3 x 108/4.3 x 10-8 = 6.977 x 1015 Hz.
-- The energy of each photon of that light is (frequency) x (Planck's Konstant)
= (6.977 x 1015) x (6.63 x 10-34) = 4.626 x 10-18 jouleper photon
-- The total energy of a beam of that light depends on how many photons of it
are in the beam. If the beam hasn't enough energy for you, you simply use a
higher-power light bulb.

∙ 7y agoE = Plank's constant x frequency
frequency = speed of light/wavength = 2.998x10^8 m/sec/4.5x10^-7 m = 6.66x10^14 sec^-1
E = 6.626x10^-34 Jsec x 6.66x10^14 sec^-1 = 4.4x10^-19 J

Do violet light and red light have the same energy?
Energy = Planck's Constant * wavelength The lights will not have the same energy is the wavelength varies.
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 and light spectrum. Greater Momentum= Ultraviolet lamp. Electron diffraction, Wavelength=h(planck's constant) / momentum. rearrange it as M=h/W. The greater the wavelength, the smaller the momentum, and visa versa.
The energy of a photon is related to its?
... frequency of the electromagnetic radiation of which the photon is a particle.
What is the lowest light energy in the electromagnetic spectrum?
answer: The wavelength of light is measured in full integers of Planks constant so by definition, the least energy a photon can Carrie is define by Plank's constant and is referred to has the Planck energy.
If the wavelength of a radio photon from an AM radio station is 220 m what is its energy?
You can use the formula: E = hc / lambda Where: "h" is Planck's constant; "c" is the speed of light; "lambda" is the wavelength.
How do determine planck's constant?
Energy/frequency or energy*wavelength/speed of light.
Do violet light and red light have the same energy?
Energy = Planck's Constant * wavelength The lights will not have the same energy is the wavelength varies.
What is the base unit of Plancks constant?
Planck's constant relates the energy level of radiation due to electrons moving from one energy level to another, by the formula Energy = (Planck's constant) x (frequency of radiation). Therefore the dimensions of Planck's constant are (energy)/(frequency) which means Joules x seconds In fact Planck's constant = 6.67 x 10-34 joule.seconds.
How are wavelength frequency and energy are related?
Energy of light photons is related to frequency as Energy = h(Planck's constant)* frequency Frequency = velocity of wave / wavelength So energy = h * velocity of the wave / wavelength
How are the wavelength and energy of electromagnetic radiation related?
The energy of one photon is given by its frequency X planck's constant Its frequency is given by the speed of light divided by the wavelength.

... frequency of the electromagnetic radiation of which the photon is a particle.
What is the Mathematical relation between energy of radiation and wavelength?
The energy of a basic unit of electromagnetic energy, the photon, is related directly to its frequency by a scaling factor called Planck's Constant, and the equation is often written e = Hf where e is energy unit, H is Planck's Constant and f is frequency unit.
What is the lowest light energy in the electromagnetic spectrum?
answer: The wavelength of light is measured in full integers of Planks constant so by definition, the least energy a photon can Carrie is define by Plank's constant and is referred to has the Planck energy.
How does Planck's constant work?
Planck's Constant defines a minimum momentum moment h=mvw where w is wavelength. Planck's Constant is the product of electric charge Q and magnetic charge W (Weber voltsecond). The Planck energy E= hf = QWf = QV or WI. Planck's Constant also defines a minimum energy moment Ew=hc. Planck's Constant is related to the electromagnetic wave in "free Space" h=QW and the "free space" impedance z = W/Q = 375 Ohms. h= zQ^2.
How are the energy and wavelength radiation related?
Energy and wavelength are related by Planck's Energy formula E = hf = hc/w where w is the wavelength.
If the wavelength of a radio photon from an AM radio station is 220 m what is its energy?
You can use the formula: E = hc / lambda Where: "h" is Planck's constant; "c" is the speed of light; "lambda" is the wavelength.
