Wavelength Formula:
| From: | To: |
Wavelength calculation determines the distance between consecutive crests of a wave, typically measured in meters. It's a fundamental concept in physics, particularly in wave mechanics and electromagnetic theory.
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 essential in various fields including telecommunications, radio broadcasting, optics, astronomy, and medical imaging. It helps in designing antennas, optical systems, and understanding electromagnetic spectrum properties.
Tips: Enter frequency in Hertz (Hz). The frequency must be a positive value 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 have an inverse relationship. As frequency increases, wavelength decreases, and vice versa, when the wave speed is constant.
Q2: Can this calculator be used for sound waves?
A: No, this calculator uses the speed of light (3×10^8 m/s). For sound waves, you would need to use the speed of sound (approximately 343 m/s in air at 20°C).
Q3: What are common frequency ranges and their corresponding wavelengths?
A: Radio waves (3 kHz-300 GHz) have wavelengths from 100 km to 1 mm, visible light (400-790 THz) has wavelengths from 380-750 nm.
Q4: Why is the speed of light constant in vacuum?
A: The speed of light in vacuum is a fundamental constant of nature (approximately 299,792,458 m/s) and is the maximum speed at which all energy, matter, and information can travel.
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.
