Wavelength Equation:
| From: | To: |
The wavelength equation calculates the wavelength of electromagnetic waves from frequency using the fundamental relationship λ = c / f, 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: This equation demonstrates 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, radio astronomy, 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 greater than zero. The calculator will automatically compute the corresponding wavelength in meters.
Q1: What is the speed of light value used in this calculation?
A: The calculator uses the standard value of 3×10^8 meters per second, which is the speed of light in a vacuum.
Q2: Does this equation work for all electromagnetic waves?
A: Yes, this fundamental relationship applies to all electromagnetic radiation including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Q3: What are typical wavelength ranges?
A: Wavelengths range from picometers (gamma rays) to kilometers (radio waves). Visible light ranges from approximately 380-750 nanometers.
Q4: How does wavelength relate to energy?
A: Energy is inversely proportional to wavelength (E = hc/λ), meaning shorter wavelengths correspond to higher energy radiation.
Q5: Can this be used for sound waves?
A: No, this specific equation is for electromagnetic waves. For sound waves, the equation is λ = v/f where v is the speed of sound in the medium.
