Wavelength Formula:
From: | To: |
The wavelength formula calculates the distance between consecutive crests of a wave from its frequency and propagation speed. It is fundamental in physics, particularly in wave mechanics and electromagnetic theory.
The calculator uses the wavelength formula:
Where:
Explanation: The formula shows the inverse relationship between wavelength and frequency - as frequency increases, wavelength decreases, and vice versa.
Details: Wavelength calculation is essential in various fields including telecommunications, optics, acoustics, and radio engineering. It helps determine signal characteristics, antenna design, and wave behavior in different media.
Tips: Enter frequency in Hertz (Hz) and wave speed in meters per second (m/s). For light in vacuum, use c = 3 × 10^8 m/s. All values must be positive numbers.
Q1: What is the relationship between frequency and wavelength?
A: Frequency and wavelength have an inverse relationship. When frequency increases, wavelength decreases, and vice versa, assuming constant wave speed.
Q2: What is the speed of light used in calculations?
A: The speed of light in vacuum is approximately 3 × 10^8 m/s (299,792,458 m/s exactly). This value is pre-filled as the default speed value.
Q3: Can this calculator be used for sound waves?
A: Yes, simply input the speed of sound (approximately 343 m/s in air at 20°C) instead of the speed of light.
Q4: What are typical wavelength ranges?
A: Wavelengths vary greatly - radio waves can be kilometers long, visible light is 380-750 nm, while gamma rays have wavelengths smaller than atoms.
Q5: How does medium affect wavelength?
A: When waves enter a different medium, frequency remains constant but speed changes, causing wavelength to change proportionally to the speed change.
