Wavelength to Frequency Formula:
From: | To: |
The wavelength to frequency equation relates the wavelength of a wave to its frequency using the speed of propagation. It's fundamental in physics, particularly in wave mechanics and electromagnetism.
The calculator uses the wavelength to frequency equation:
Where:
Explanation: The equation shows that frequency is inversely proportional to wavelength - as wavelength increases, frequency decreases, and vice versa.
Details: Calculating frequency from wavelength is essential in many fields including radio communications, optics, acoustics, and quantum mechanics.
Tips: Enter wavelength in meters and speed of propagation in m/s (default is speed of light: 299,792,458 m/s). All values must be positive numbers.
Q1: What units should I use for wavelength?
A: The calculator expects wavelength in meters. For other units (nm, μm, etc.), convert to meters first (1 nm = 10⁻⁹ m).
Q2: Can I use this for sound waves?
A: Yes, just replace the speed of light with the speed of sound in your medium (about 343 m/s in air at 20°C).
Q3: What if I know frequency and want wavelength?
A: Rearrange the equation: λ = c/f. We may add a frequency to wavelength calculator in the future.
Q4: Why is the speed of light the default?
A: This equation is most commonly used for electromagnetic waves, which travel at light speed in a vacuum.
Q5: How precise are the results?
A: Results are precise to 2 decimal places. For scientific work, consider using more precise input values.
