Wavelength Equation:
From: | To: |
The wavelength equation calculates the wavelength of electromagnetic waves from frequency using the speed of light. It's fundamental in physics, engineering, and telecommunications for understanding wave properties.
The calculator uses the wavelength equation:
Where:
Explanation: The equation shows the inverse relationship between wavelength and frequency - higher frequencies result in shorter wavelengths.
Details: Wavelength calculation is essential for antenna design, radio communications, optical systems, and understanding electromagnetic spectrum properties across different applications.
Tips: Enter frequency in Hertz (Hz). The value must be positive and greater than zero. The calculator will compute the corresponding wavelength in meters.
Q1: What is the speed of light constant?
A: The speed of light in vacuum is exactly 299,792,458 m/s, but 3×10⁸ m/s is commonly used for calculations.
Q2: Can this equation be used for sound waves?
A: No, this equation is specifically for electromagnetic waves. For sound waves, use λ = v/f where v is the speed of sound.
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: How does wavelength relate to energy?
A: Energy is inversely proportional to wavelength (E = hc/λ), meaning shorter wavelengths correspond to higher energy photons.
Q5: What units can wavelength be expressed in?
A: While meters are standard, wavelengths are often expressed in nanometers (nm) for light, centimeters (cm) for microwaves, or kilometers (km) for radio waves.
