# What is the frequency of a photon of energy 58eV?

• bruinboy28
In summary, the frequency of a photon with energy 58 eV can be calculated using the formula frequency = energy/h, where h is Planck's constant. Plugging in the value of 58 eV for energy and the value of Planck's constant (4.135667662 × 10^-15 eV•s), we get a frequency of approximately 1.404 × 10^17 Hz. The frequency of a photon is directly proportional to its energy, as described by the equation E = hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency. The frequency of a photon can change when it interacts with matter, particles, or due to the Dop

## Homework Statement

What is the frequency of a photon of energy 58eV?

## Homework Equations

E=hF

where H is Planck's constant, 6.63x10^-34

## The Attempt at a Solution

58/ (6.63x10^-34) = 8.75e34

that is not correct.

Do i have the energy eV into a certain unit?

Hint: 1eV = 1.602E-19 J

When in doubt, put everything in units of MKS (meters, seconds, and kg).

MKS energy unit is the Joule = kg * m^2 / s^2

## 1. What is the frequency of a photon with energy 58 eV?

The frequency of a photon with energy 58 eV can be calculated using the formula: frequency = energy/h, where h is Planck's constant. Plugging in the value of 58 eV for energy and the value of Planck's constant (4.135667662 × 10^-15 eV•s), we get a frequency of approximately 1.404 × 10^17 Hz.

## 2. How is the frequency of a photon related to its energy?

The frequency of a photon is directly proportional to its energy. This means that as the energy of a photon increases, its frequency also increases. This relationship is described by the equation E = hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency.

## 3. Can the frequency of a photon change?

Yes, the frequency of a photon can change. This can happen when a photon interacts with matter or other particles, causing its energy to change. The frequency of a photon can also be affected by the Doppler effect, which occurs when there is relative motion between the source of the photon and the observer.

## 4. What units are used to measure the frequency of a photon?

The frequency of a photon is typically measured in hertz (Hz), which is equivalent to 1 cycle per second. However, since photons have very high frequencies, they are often measured in kilohertz (kHz), megahertz (MHz), or even gigahertz (GHz).

## 5. Is there a maximum frequency for a photon?

According to current scientific theories, there is no upper limit to the frequency of a photon. However, as the frequency increases, the energy of the photon also increases, and at very high frequencies, the behavior of photons may be affected by quantum gravity effects. Additionally, some theories suggest that at extremely high frequencies, the concept of frequency itself may break down.
