Frequency Equation:
From: | To: |
The frequency of a photon is the number of wave cycles that pass a given point per second, calculated as the inverse of the time period. For photons, frequency is directly related to the energy of the photon.
The calculator uses the frequency equation:
Where:
Explanation: The frequency is simply the reciprocal of the time period. For photons, this frequency can then be used to calculate energy using Planck's equation.
Details: Calculating photon frequency is essential in quantum mechanics, spectroscopy, and understanding electromagnetic radiation properties. It connects the wave and particle nature of light.
Tips: Enter the time period in seconds. The value must be positive (T > 0). The calculator will compute the corresponding frequency in Hertz.
Q1: What's the difference between frequency and period?
A: Frequency (f) is the number of cycles per second, while period (T) is the time for one complete cycle. They are inversely related.
Q2: How does frequency relate to photon energy?
A: Photon energy is calculated by E = h×f, where h is Planck's constant (6.626×10⁻³⁴ J·s).
Q3: What are typical frequency values for visible light?
A: Visible light ranges from about 430 THz (red) to 750 THz (violet).
Q4: Can this calculator be used for any wave?
A: Yes, the f = 1/T relationship applies to all periodic waves, not just photons.
Q5: Why is frequency important in quantum mechanics?
A: Frequency determines a photon's energy and is fundamental to wave-particle duality.
