Wavelength to Frequency Formula:

| From: | To: |
Wavelength to frequency conversion is a fundamental concept in physics that relates the distance between successive crests of a wave (wavelength) to the number of wave cycles per second (frequency). This relationship is particularly important in electromagnetic wave studies.
The calculator uses the wavelength to frequency formula:
Where:
Explanation: The frequency of a wave is inversely proportional to its wavelength. As wavelength increases, frequency decreases, and vice versa.
Details: Calculating frequency from wavelength is essential in various fields including telecommunications, radio broadcasting, astronomy, and spectroscopy. It helps determine the properties of electromagnetic waves and their applications.
Tips: Enter the wavelength in meters. The value must be greater than zero. The calculator will compute the corresponding frequency using the speed of light constant.
Q1: Why is the speed of light used in this calculation?
A: For electromagnetic waves (including light, radio waves, etc.), the speed of propagation is constant at approximately 3×10^8 m/s in a vacuum.
Q2: Can this calculator be used for sound waves?
A: No, this calculator is specifically for electromagnetic waves. For sound waves, you would need to use the speed of sound (approximately 343 m/s in air) instead of the speed of light.
Q3: What are common wavelength ranges?
A: Radio waves can have wavelengths from millimeters to kilometers, visible light ranges from 380-750 nanometers, and gamma rays have wavelengths smaller than atoms.
Q4: How does frequency relate to energy?
A: According to Planck's equation (E = hf), energy is directly proportional to frequency, where h is Planck's constant. Higher frequency waves carry more energy.
Q5: What if my wavelength is in different units?
A: Convert your wavelength to meters before using this calculator. Common conversions: 1 nanometer = 10^-9 meters, 1 micrometer = 10^-6 meters.
