Wavelength Formula:
| From: | To: |
The wavelength frequency equation relates the wavelength of a wave to its frequency and the speed of propagation. For electromagnetic waves, the speed is the speed of light (c = 3×10⁸ m/s).
The calculator uses the wavelength formula:
Where:
Explanation: The equation shows the inverse relationship between wavelength and frequency - as frequency increases, wavelength decreases, and vice versa.
Details: Wavelength calculation is crucial in various fields including telecommunications, radio broadcasting, optics, and electromagnetic spectrum analysis. It helps determine signal propagation characteristics and antenna design requirements.
Tips: Enter frequency in Hertz (Hz). The value must be greater than 0. The calculator will compute the corresponding wavelength in meters.
Q1: What is the relationship between wavelength and frequency?
A: Wavelength and frequency have an inverse relationship. As frequency increases, wavelength decreases, and vice versa, when the wave speed is constant.
Q2: Why is the speed of light used in this calculation?
A: For electromagnetic waves (including radio waves, light, etc.), the speed of propagation in vacuum is constant at approximately 3×10⁸ m/s.
Q3: Can this calculator be used for sound waves?
A: No, this calculator uses the speed of light. For sound waves, you would need to use the speed of sound (approximately 343 m/s in air at 20°C).
Q4: What are typical frequency ranges for different applications?
A: Radio waves: 3 kHz-300 GHz, Microwaves: 300 MHz-300 GHz, Infrared: 300 GHz-430 THz, Visible light: 430-750 THz, UV: 750 THz-30 PHz.
Q5: How does wavelength affect signal propagation?
A: Longer wavelengths generally travel farther and penetrate obstacles better, while shorter wavelengths carry more data but have shorter range and poorer penetration.
