Energy to Frequency Formula:
| From: | To: |
The energy to frequency conversion is based on Planck's equation, which relates the energy of a photon to its frequency. This fundamental relationship is crucial in quantum mechanics and electromagnetic theory.
The calculator uses the formula:
Where:
Explanation: This equation demonstrates the direct proportionality between the energy of a photon and its frequency, with Planck's constant as the proportionality factor.
Details: Calculating frequency from energy is essential in various fields including quantum physics, spectroscopy, photonics, and telecommunications. It helps determine the characteristics of electromagnetic radiation and quantum particles.
Tips: Enter energy in joules and Planck's constant in joule-seconds. The default value for Planck's constant is 6.626 × 10⁻³⁴ J·s, which is the standard value. Both values must be positive numbers.
Q1: What is Planck's constant?
A: Planck's constant (h) is a fundamental physical constant that relates the energy of a photon to its frequency. Its value is approximately 6.626 × 10⁻³⁴ joule-seconds.
Q2: What are typical energy values for photons?
A: Photon energies vary widely. Visible light photons have energies around 10⁻¹⁹ J, while gamma rays can have energies up to 10⁻¹³ J or higher.
Q3: Can this formula be used for all types of electromagnetic radiation?
A: Yes, the formula applies to all electromagnetic radiation, from radio waves to gamma rays, as it's based on fundamental quantum principles.
Q4: Why is frequency important in physics?
A: Frequency determines many properties of waves, including color for visible light, penetration ability for different radiation types, and energy content in quantum mechanics.
Q5: What are the units of measurement?
A: Energy is measured in joules (J), Planck's constant in joule-seconds (J·s), and the resulting frequency in hertz (Hz), where 1 Hz = 1 cycle per second.
