Wavelength and Frequency Equation:
From: | To: |
The wavelength and frequency equation describes the fundamental relationship between the wavelength (λ) of a wave, its frequency (f), and the speed of propagation (c). This equation is fundamental in wave physics and electromagnetic theory.
The calculator uses the wavelength equation:
Where:
Explanation: The equation shows that wavelength is inversely proportional to frequency - higher frequency waves have shorter wavelengths, and vice versa.
Details: Calculating wavelength is crucial for understanding wave behavior, designing communication systems, analyzing electromagnetic spectra, and various applications in physics and engineering.
Tips: Enter frequency in Hertz and speed of light in m/s (default is 300,000,000 m/s for vacuum). All values must be valid (frequency > 0, speed > 0).
Q1: What is the speed of light in different media?
A: The speed of light varies in different media. In vacuum it's 3×10⁸ m/s, but it's slower in water, glass, and other materials due to refractive index.
Q2: How does wavelength relate to energy?
A: For electromagnetic waves, shorter wavelengths correspond to higher energy photons according to E = hc/λ, where h is Planck's constant.
Q3: What are typical wavelength ranges?
A: Radio waves: 1mm-100km, Microwaves: 1mm-1m, Infrared: 700nm-1mm, Visible light: 380-750nm, UV: 10-380nm, X-rays: 0.01-10nm, Gamma rays: <0.01nm.
Q4: Can this equation be used for sound waves?
A: Yes, the same principle applies to sound waves, but use the speed of sound (approximately 343 m/s in air at 20°C) instead of the speed of light.
Q5: What if the wave is not electromagnetic?
A: The equation λ = v/f applies to all wave types, where v is the wave speed specific to that medium and wave type.
