Frequency Formula:
| From: | To: |
The frequency of a photon refers to the number of wave cycles that pass a given point per second. It is inversely proportional to the wavelength and directly related to the photon's energy through Planck's constant.
The calculator uses the frequency formula:
Where:
Explanation: The formula shows that frequency is inversely proportional to wavelength - as wavelength increases, frequency decreases, and vice versa.
Details: Calculating photon frequency is essential in various fields including optics, quantum mechanics, telecommunications, and spectroscopy. It helps determine the energy of photons and their behavior in different media.
Tips: Enter the wavelength in meters. The value must be positive and greater than zero. The calculator will compute the corresponding frequency in hertz (Hz).
Q1: What is the relationship between frequency and energy?
A: The energy of a photon is directly proportional to its frequency: E = h × f, where h is Planck's constant (6.626 × 10⁻³⁴ J·s).
Q2: What are typical frequency ranges for visible light?
A: Visible light frequencies range from approximately 4.3 × 10¹⁴ Hz (red) to 7.5 × 10¹⁴ Hz (violet).
Q3: How does frequency relate to the electromagnetic spectrum?
A: Different frequency ranges correspond to different types of electromagnetic radiation, from radio waves (low frequency) to gamma rays (high frequency).
Q4: Why is the speed of light constant in the formula?
A: In vacuum, the speed of light is a fundamental constant (approximately 3 × 10⁸ m/s) that relates frequency and wavelength for all electromagnetic radiation.
Q5: Can this formula be used for other waves besides light?
A: Yes, the formula v = f × λ applies to all waves, where v is the wave velocity. For electromagnetic waves in vacuum, v equals c.
