Wavelength Formula:
| From: | To: |
The wavelength formula (λ = c/f) calculates the wavelength of electromagnetic waves, where λ is wavelength, c is the speed of light (3×10⁸ m/s), and f is frequency. This fundamental physics equation relates these three important wave properties.
The calculator uses the wavelength formula:
Where:
Explanation: The formula shows that wavelength is inversely proportional to frequency - higher frequencies result in shorter wavelengths, and vice versa.
Details: Wavelength calculation is essential in various fields including telecommunications, optics, astronomy, and quantum mechanics. It helps determine wave properties, design antennas, analyze light spectra, and understand electromagnetic radiation behavior.
Tips: Enter frequency in Hertz (Hz). The value must be greater than 0. The calculator will compute the corresponding wavelength in meters using the speed of light constant.
Q1: Why is the speed of light constant in this formula?
A: The speed of light in vacuum (c = 3×10⁸ m/s) is a fundamental physical constant that applies to all electromagnetic radiation regardless of frequency.
Q2: Can this formula be used for sound waves?
A: No, this specific formula is for electromagnetic waves. For sound waves, the formula is λ = v/f, where v is the speed of sound in the medium.
Q3: What are typical wavelength ranges?
A: Radio waves have wavelengths from meters to kilometers, visible light from 380-750 nanometers, and gamma rays have wavelengths smaller than atoms.
Q4: How does wavelength relate to energy?
A: Energy is inversely proportional to wavelength (E = hc/λ), meaning shorter wavelengths correspond to higher energy radiation.
Q5: What if I need to calculate frequency from wavelength?
A: You can rearrange the formula: f = c/λ. Enter the wavelength to calculate the corresponding frequency.
