Wavelength to Frequency Formula:
From: | To: |
The wavelength to frequency formula describes the relationship between the wavelength of electromagnetic waves and their frequency. It is a fundamental equation in physics that applies to all types of electromagnetic radiation, including light, radio waves, and microwaves.
The calculator uses the wavelength to frequency formula:
Where:
Explanation: The formula shows that frequency is inversely proportional to wavelength - as wavelength increases, frequency decreases, and vice versa.
Details: Calculating frequency from wavelength is essential in various fields including telecommunications, optics, astronomy, and spectroscopy. It helps determine the energy and properties of electromagnetic waves.
Tips: Enter wavelength in meters (m). The value must be greater than 0. The calculator will automatically compute the corresponding frequency in Hertz (Hz).
Q1: What is the speed of light constant?
A: The speed of light in vacuum is exactly 299,792,458 m/s, but is commonly approximated as 3×10⁸ m/s for calculations.
Q2: Can this formula be used for sound waves?
A: No, this specific formula is for electromagnetic waves. For sound waves, the formula is f = v/λ, where v is the speed of sound.
Q3: What are typical wavelength ranges?
A: Visible light: 380-750 nm, Radio waves: 1 mm-100 km, X-rays: 0.01-10 nm, Gamma rays: less than 0.01 nm.
Q4: How does wavelength relate to energy?
A: Energy is inversely proportional to wavelength (E = hc/λ), so shorter wavelengths correspond to higher energy radiation.
Q5: What units should I use for wavelength?
A: The calculator expects meters, but you can convert from other units: 1 nm = 10⁻⁹ m, 1 μm = 10⁻⁶ m, 1 mm = 10⁻³ m.
