Wavelength Equation:
| From: | To: |
The wavelength equation (λ = c / f) calculates the wavelength of electromagnetic waves from frequency, where c is the speed of light (3×10^8 m/s) and f is the frequency in hertz (Hz).
The calculator uses the wavelength equation:
Where:
Explanation: The equation 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, radio broadcasting, optics, and electromagnetic spectrum analysis. It helps determine signal propagation characteristics and antenna design requirements.
Tips: Enter frequency in hertz (Hz). The value must be positive and non-zero. The calculator will automatically compute the corresponding wavelength in meters.
Q1: What is the speed of light value used in the calculation?
A: The calculator uses c = 3×10^8 m/s, which is the standard speed of light in vacuum.
Q2: Can this equation be used for all electromagnetic waves?
A: Yes, the equation λ = c/f applies to all electromagnetic waves in vacuum, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Q3: What units should I use for frequency?
A: Frequency should be entered in hertz (Hz). For higher frequencies, you may use kHz, MHz, or GHz by converting to Hz (1 MHz = 1,000,000 Hz).
Q4: How does wavelength relate to wave properties?
A: Wavelength is the distance between successive crests of a wave and determines many wave properties including diffraction, interference patterns, and energy.
Q5: Are there any limitations to this equation?
A: The equation assumes propagation in vacuum. For waves traveling through other media, the speed of light in that specific medium should be used instead of c.
