Wavelength to Frequency Formula:
| From: | To: |
The wavelength to frequency conversion calculates the frequency of an electromagnetic wave given its wavelength, using the fundamental relationship between these two properties of waves.
The calculator uses the wavelength to frequency formula:
Where:
Explanation: This formula demonstrates the inverse relationship between wavelength and frequency - as wavelength increases, frequency decreases, and vice versa.
Details: Calculating frequency from wavelength is essential in various fields including telecommunications, radio broadcasting, optics, and electromagnetic spectrum analysis. It helps determine the properties and behavior of electromagnetic waves.
Tips: Enter the wavelength value in meters. The value must be positive and greater than zero. The calculator will automatically compute the corresponding frequency in Hertz.
Q1: 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 equal to the speed of light.
Q2: Why is the speed of light constant in this calculation?
A: The speed of light (c = 3×10⁸ m/s) is a fundamental constant in vacuum and is used as the propagation speed for all electromagnetic waves.
Q3: Can this formula be used for all types of waves?
A: While the general relationship applies to all waves, the specific formula f = c/λ is primarily for electromagnetic waves. For other wave types, the propagation speed may differ.
Q4: What are typical wavelength ranges for different applications?
A: Radio waves have wavelengths from meters to kilometers, visible light from 380-750 nanometers, while gamma rays have wavelengths smaller than atomic nuclei.
Q5: How does medium affect wavelength and frequency?
A: Frequency remains constant when a wave changes medium, but wavelength changes as the speed of propagation changes in different media.
