Frequency Formula:
| From: | To: |
The wavelength to frequency equation is a fundamental relationship in physics and chemistry that connects the wavelength of electromagnetic radiation to its frequency using the speed of light constant.
The calculator uses the wavelength to frequency equation:
Where:
Explanation: This equation demonstrates the inverse relationship between wavelength and frequency - as wavelength increases, frequency decreases, and vice versa.
Details: Calculating frequency from wavelength is crucial in spectroscopy, quantum chemistry, electromagnetic wave analysis, and various applications in physics and engineering where wave properties are studied.
Tips: Enter wavelength in meters. The value must be valid (wavelength > 0). The calculator will automatically compute the corresponding frequency using the speed of light constant.
Q1: Why is the speed of light constant important in this calculation?
A: The speed of light (c = 3×10⁸ m/s) is a fundamental constant that relates the wavelength and frequency of all electromagnetic radiation in a vacuum.
Q2: What units should I use for wavelength?
A: The calculator uses meters (m) for wavelength. For very small wavelengths (like visible light), you may need to convert from nanometers (1 nm = 10⁻⁹ m).
Q3: Can this calculator be used for all types of electromagnetic radiation?
A: Yes, the equation applies to all electromagnetic waves including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Q4: What is the relationship between wavelength and frequency?
A: Wavelength and frequency have an inverse relationship. As wavelength increases, frequency decreases, and vice versa, with their product always equal to the speed of light.
Q5: How accurate is this calculation?
A: The calculation is mathematically exact based on the fundamental relationship f = c/λ. Accuracy depends on the precision of your wavelength measurement and the accepted value of the speed of light.
