Wavelength to Frequency Formula:
From: | To: |
The wavelength to frequency formula calculates the frequency of a wave from its wavelength using the speed of light. This relationship is fundamental in physics, particularly in electromagnetics and wave theory.
The calculator uses the wavelength to frequency formula:
Where:
Explanation: The frequency of a wave is inversely proportional to its wavelength, with the speed of light as the constant of proportionality.
Details: Calculating frequency from wavelength is essential in various fields including telecommunications, radio broadcasting, optics, and spectroscopy. It helps determine the properties of electromagnetic waves.
Tips: Enter wavelength in meters. The value must be valid (wavelength > 0). The calculator will compute the corresponding frequency in hertz (Hz).
Q1: Why is the speed of light used in this formula?
A: For electromagnetic waves, the speed of propagation is the speed of light (c = 3×10⁸ m/s), making it the appropriate constant for these calculations.
Q2: Can this formula be used for other types of waves?
A: Yes, but with the appropriate speed constant. For sound waves, use the speed of sound instead of the speed of light.
Q3: What are typical wavelength values?
A: Wavelengths vary greatly: radio waves (meters to kilometers), visible light (400-700 nanometers), X-rays (0.01-10 nanometers).
Q4: How does frequency relate to energy?
A: Higher frequency waves have higher energy (E = hf, where h is Planck's constant).
Q5: What if I have frequency and want wavelength?
A: Rearrange the formula: λ = c/f. You can calculate wavelength if you know the frequency.
