Wavelength Formula:
| From: | To: |
The wavelength formula calculates the physical length of one complete wave cycle in a radio frequency signal. It's a fundamental relationship in physics and radio communications that connects frequency and wavelength through the speed of light.
The calculator uses the wavelength formula:
Where:
Explanation: The formula shows the inverse relationship between frequency and wavelength - as frequency increases, wavelength decreases, and vice versa.
Details: Wavelength calculation is crucial in RF engineering, antenna design, wireless communications, and electromagnetic theory. It helps determine antenna size, signal propagation characteristics, and frequency allocation.
Tips: Enter frequency in Hertz (Hz). All values must be valid (frequency > 0). The calculator will automatically compute the corresponding wavelength in meters.
Q1: Why is the speed of light used in the formula?
A: Radio waves are electromagnetic radiation that travel at the speed of light, making c the fundamental constant that relates frequency and wavelength.
Q2: Can I use different units for frequency?
A: Yes, but you must convert to Hertz first (1 kHz = 1000 Hz, 1 MHz = 1,000,000 Hz, 1 GHz = 1,000,000,000 Hz).
Q3: What are typical wavelength values for radio frequencies?
A: For example: 100 MHz ≈ 3 meters, 1 GHz ≈ 30 cm, 10 GHz ≈ 3 cm, showing how wavelength decreases as frequency increases.
Q4: How does wavelength affect antenna design?
A: Antennas are typically designed around fractions of wavelength (¼λ, ½λ, etc.), so knowing the wavelength is essential for proper antenna sizing and performance.
Q5: Is the speed of light constant in all materials?
A: No, the speed of light and therefore wavelength changes when waves pass through different media. This formula uses the speed of light in vacuum (3×10⁸ m/s).
