The Frequency of Radiation Calculator is a scientific tool used to determine the frequency of radiation emitted based on its energy. It uses Planck’s constant as a fundamental component in the calculation. This is essential in fields like physics, quantum mechanics, and spectroscopy.

Formula
The formula to calculate the frequency of radiation is:
Frequency of Radiation (fr) = Energy (E) ÷ Planck’s Constant (h)

How to Use

  1. Input the energy value in joules in the first field.
  2. Enter Planck’s constant in the second field (default value is 6.62607015 × 10⁻³⁴ J·s).
  3. Click the “Calculate” button.
  4. The frequency of radiation will be displayed in hertz (Hz).

Example
Suppose the energy of radiation is 3.3 × 10⁻¹⁹ joules. Using the formula:
fr = 3.3 × 10⁻¹⁹ ÷ 6.62607015 × 10⁻³⁴
fr = 4.98 × 10¹⁴ Hz
