If you mean light of a given wavelength, then the energy E per photon is given by the formula:
E = hc/λ,
where h is Planck's constant, c is the speed of light and λ is the wavelength.

- use a Maxwell Bridge to accurately measure the inductance of an inductor
- use a Wheatstone Bridge to accurately measure the resistance of the inductor
- use an accurate ammeter and voltmeter to determine the impedance of the inductor
- use the resistance and impedance to determine the inductive reactance (XL)
- since XL = 2 pi f L, you can then work out f, the frequency
Well, that's how you could do it, theoretically. Not quite as easy in practise, though, as accuracy would be essential! I recommend that you ask your supply company!!!

E=hf
where E=energy

But if you are given the wavelength, you might need this:
since v= λ
x f
where v=speed
? λ=wavelength? f=frequency
and v=c= speed of light=
3x108m/s
Hence, E= hf= h(c÷
λ)

∙ 9y agoThe relation is the following:
e = h.f, where:
- e is the energy in joules
- h is the Planck constant: 6,626 069 572 9.10-34 joule.second
- f is the frequency in cycles/second
And consequently the energy is 2,2065.10-19 joules

Find the energy of a photon whose frequency is 5x10 12 Hz?
what is the energy of a photon that has a frequency of 5.0x1014 Hz?
What is the energy of a photon having a frequency of 410E 7 hz?
use the equation E = hf where h is plancks constant E = 410E 7 * 6.63E -34 E = 2.7183E -23 joules
What exactly does a frequency converter convert?
A frequency converter converts an alternating current from one frequency to another. This is typically measured in Hertz (Hz).
How is frequency of an EM wave related to its energy?
The higher the frequency of a wave, the higher its energy
What is the energy of an electromagnetic wave with a frequency of 8x1012 Hz?
5.3x10^-21
Are joules used to measure frequency?
No, the joule (J) is a unit of energy. Frequency is measured in cycles per second, which is also called hertz(Hz).
What is the energy of photon that emits a light of frequency (4.47)(10 exponent 14) Hz?
The energy is 2,9619.e-19 J.
Calculate energy of photon with frequency of 5×10 to the exponent 20 Hz?
The energy of a photon is given by the equation: E = h * f where E is the energy of the photon, h is Planck's constant, and f is the frequency of the photon. Plugging in the given frequency of 5 × 10^20 Hz, and using the value of Planck's constant h = 6.626 x 10^-34 joule seconds, we get: E = (6.626 x 10^-34 J s) * (5 x 10^20 Hz) = 3.313 x 10^-13 joules Therefore, the energy of a photon with a frequency of 5 × 10^20 Hz is approximately 3.313 x 10^-13 joules.
What is the energy of a photon the emits a light of frequency 4.47 x Hz?
The energy of a photon when frequency is known is E = hv, where E is energy in Joules, h is Planck's constant, 6.626 x 10-34 Joule•second, and v is frequency.E = 6.626 x 10-34 J•s x 4.47 x 1014 Hz = 2.96 x 10-19 Joules
What is the energy of a photon with the frequency 5 times 10 to the14th power Hz?
The energy is E=hf= 2/3E-33 x 5E14= 1/3 E-18 Joules.
How do you convert Hz to GHz?
1 GHz = 1*109 Hz. To convert GHz to Hz multiply by 1*109 To convert Hz to GHz divide by 1*109
How much time is 10 Hz?
Hz is short for hertz. It is not a time, but a frequency. Time is measured in seconds, Hz is equivalent to 1/seconds. Therefore, you can't convert between time and frequency.
Find the energy of a photon whose frequency is 5x10 12 Hz?
what is the energy of a photon that has a frequency of 5.0x1014 Hz?
How do you convert hz to decibles?
You don't. Hz (always capitalized) is the unit for measuring frequency or pitch. dB is the unit for measuring amplitude or relative loudness of the sound. You cannot convert a frequency measurement to an amplitude measurement.
How do you convert Hz to Watts?
You cant. Hz measures frequency, where as Watts is a measurement of power.
How can you determine the frequency of a light wave?
to find the frequency of a light wave you need to know its wavelength. The frequency is equal to the speed of light (3x10^8 m/s) divided by the wavelength in metres. Alternatively, if you were given the energy of each photon of light in joules you could just divide the energy by plancks constant (6.63x10^-34) to leave you with the frequency in Hz.
What is the energy of a photon having a frequency of 410E 7 hz?
use the equation E = hf where h is plancks constant E = 410E 7 * 6.63E -34 E = 2.7183E -23 joules
