Wavelength Formula:
| From: | To: |
The wavelength formula calculates the distance between consecutive crests of a wave using the relationship between the speed of light and frequency. It's fundamental in physics, optics, and telecommunications.
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 for designing antennas, understanding electromagnetic spectrum properties, optical communications, and various scientific applications involving wave phenomena.
Tips: Enter frequency in Hertz (Hz). The value must be positive and greater than zero. The calculator will automatically compute the corresponding wavelength in meters.
Q1: What is the relationship between frequency and wavelength?
A: Frequency and wavelength are inversely proportional. As frequency increases, wavelength decreases, and vice versa, when the wave speed is constant.
Q2: Why is the speed of light used in this formula?
A: For electromagnetic waves (including light, radio waves, etc.), the speed of propagation in vacuum is constant at approximately 3×10^8 m/s.
Q3: Can this formula be used for other types of waves?
A: Yes, the general formula λ = v/f applies to all waves, where v is the wave speed. For sound waves, you would use the speed of sound instead of light.
Q4: What are typical wavelength ranges for different applications?
A: Radio waves: meters to kilometers, Microwaves: millimeters to centimeters, Visible light: 380-750 nanometers, X-rays: 0.01-10 nanometers.
Q5: How does wavelength affect signal propagation?
A: Longer wavelengths generally travel farther and penetrate obstacles better, while shorter wavelengths carry more information but have shorter range and poorer penetration.
