Calculation Formula

f = c / (λ * n)

Where:
f = Absorption Frequency (in Hz)
c = Speed of light in vacuum (approximately 3×10⁸ m/s)
λ = Wavelength (in meters)
n = Refractive Index of the medium

Result

Absorption Frequency: 0 Hz

How to Use the Calculator

  1. Enter the wavelength of light in meters in the "Wavelength (λ) in meters" field.
  2. Enter the refractive index of the medium in which the light is traveling in the "Refractive Index (n)" field.
  3. Click the "Calculate" button to compute the absorption frequency.
  4. The result will be displayed in Hz (Hertz).
  5. Use the "Reset" button to clear all inputs and results.

Understanding Absorption Frequency

Absorption frequency is the frequency at which light is absorbed by a medium. This occurs when the energy of the light matches the energy levels of the atoms or molecules in the medium, causing them to transition to higher energy states.

The formula used in this calculator is: f = c / (λ * n), where:

  • f is the absorption frequency in Hertz (Hz)
  • c is the speed of light in a vacuum (approximately 3×10⁸ meters per second)
  • λ is the wavelength of the light in meters
  • n is the refractive index of the medium

Example

If light with a wavelength of 500 nm (0.0000005 meters) travels through water (refractive index ≈ 1.33), the absorption frequency would be:

f = 3×10⁸ / (0.0000005 * 1.33) ≈ 4.55×10¹⁴ Hz

Applications

This calculator is useful in fields such as physics, chemistry, and engineering for analyzing light-matter interactions. It helps in understanding how different materials affect the frequency of light as it passes through them.
