How do i convert Energy (joules) into frequency (Hz)?

Answer 1

To convert energy in joules to frequency in hertz, you can use the Planck-Einstein relation, E = hf, where E is the energy in joules, h is the Planck constant (6.626 x 10^-34 Js), and f is the frequency in hertz. Rearrange the equation to solve for frequency: f = E / h. Simply divide the energy in joules by the Planck constant to calculate the frequency in hertz.

Answer 2

To convert energy in joules to frequency in hertz, you need additional information such as the nature of the energy source. The relationship between energy and frequency depends on the specific system or phenomenon involved. It's not a straightforward conversion without more context.

Answer 3

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.

Answer 4

You don't need to 'calculate' the frequency of your power supply, as it's openly publicised. However, if you want to do so as an academic exercise, then you could do so as follows (but you'd need very accurate instruments, and you'd need to take very careful measurements!):

1. use a Maxwell Bridge to accurately measure the inductance of an inductor
2. use a Wheatstone Bridge to accurately measure the resistance of the inductor
3. use an accurate ammeter and voltmeter to determine the impedance of the inductor
4. use the resistance and impedance to determine the inductive reactance (XL)
5. 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!!!

Answer 5

You can just use frequency to calculate energy

E=hf

where E=energy

h=planck's constant=6.626×

10−34

J/s

f= frequency

?

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)

Answer 6

The 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

Answer 7

The 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

Answer 8

E=hf, where h is Plank's Constant (look it up for the value)

Answer 9

Given wavelength w, the power is h(c/w)^2 = hc^2/w^2 = 6E-17/w^2

Answer 10

Photon energy = (frequency) times (Planck's Konstant)
