The Absorption Frequency Calculator helps you determine the frequency at which a molecule absorbs energy. This frequency is crucial in various scientific fields, such as spectroscopy, chemistry, and physics. By calculating the absorption frequency, you can understand the energy levels within a molecule and how it interacts with electromagnetic radiation.

### Formula of Absorption Frequency Calculator

The formula to calculate the absorption frequency (ν) is:

Where:

- ν is the absorption frequency in Hertz (Hz)
- ΔE is the energy difference between the two energy levels in Joules (J)
- h is Planck's constant, approximately 6.626 x 10^-34 Joule seconds (Js)

To use this formula, divide the energy difference (ΔE) by Planck's constant (h) to get the absorption frequency (ν).

### Common Terms and Conversion Table

Here is a table with general terms and common conversions related to absorption frequency:

Term | Definition |
---|---|

Absorption Frequency (ν) | The frequency at which a molecule absorbs energy, measured in Hertz (Hz). |

Energy Difference (ΔE) | The difference in energy between two levels, measured in Joules (J). |

Planck's Constant (h) | A physical constant that relates the energy of a photon to its frequency, approximately 6.626 x 10^-34 Joule seconds (Js). |

### Example of Absorption Frequency Calculator

Let's go through an example to illustrate how to use the Absorption Frequency Calculator.

Suppose we have an energy difference (ΔE) of 3.0 x 10^-19 Joules between two energy levels. To find the absorption frequency (ν), we use the formula:

ν = ΔE / h

Substituting the given values:

ν = (3.0 x 10^-19 J) / (6.626 x 10^-34 Js)

ν ≈ 4.52 x 10^14 Hz

So, the absorption frequency is approximately 4.52 x 10^14 Hz.
