Wavelength Formula:
| From: | To: |
The wavelength formula calculates the distance between consecutive points of the same phase in a wave. It is derived from the fundamental relationship between the speed of light, frequency, and wavelength in electromagnetic waves.
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, radio broadcasting, optics, astronomy, and electromagnetic spectrum analysis. It helps determine the properties and behavior of electromagnetic waves.
Tips: Enter frequency in Hertz (Hz). The value must be greater than 0. The calculator will automatically compute the corresponding wavelength in meters.
Q1: What is the relationship between frequency and wavelength?
A: Frequency and wavelength have an inverse relationship. As frequency increases, wavelength decreases, and vice versa, when the speed of light remains constant.
Q2: What are typical frequency ranges for different applications?
A: Radio waves: 3Hz-300GHz, Microwaves: 300MHz-300GHz, Infrared: 300GHz-430THz, Visible light: 430THz-750THz, UV: 750THz-30PHz.
Q3: Why is the speed of light constant in the formula?
A: In vacuum, the speed of light is a fundamental physical constant (approximately 3×10^8 m/s) that remains unchanged regardless of frequency or wavelength.
Q4: Can this formula be used for sound waves?
A: For sound waves, use λ = v/f where v is the speed of sound in the medium (approximately 343 m/s in air at 20°C).
Q5: How does wavelength affect wave propagation?
A: Longer wavelengths generally travel farther and penetrate obstacles better, while shorter wavelengths provide better resolution and are more directional.
