Wavelength Formula:
| From: | To: |
The wavelength and frequency formula describes the relationship between the wavelength (λ) of a wave, its frequency (f), and the speed of propagation (c). For electromagnetic waves, the speed of light (c = 3×10^8 m/s) is used.
The calculator uses the wavelength formula:
Where:
Explanation: The formula shows that wavelength is inversely proportional to frequency - higher frequencies correspond to shorter wavelengths, and vice versa.
Details: Calculating wavelength is essential in various fields including telecommunications, radio broadcasting, optics, and electromagnetic spectrum analysis. It helps determine wave properties and behavior in different media.
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 relationship between wavelength and frequency?
A: Wavelength and frequency have an inverse relationship. As frequency increases, wavelength decreases, and vice versa, when the wave speed is constant.
Q2: Can this formula be used for all types of waves?
A: While the basic relationship applies to all waves, the speed value (c) changes depending on the medium and type of wave. For electromagnetic waves in vacuum, c = 3×10^8 m/s.
Q3: What are typical frequency ranges for different applications?
A: Radio waves: 3 kHz-300 GHz, Microwaves: 300 MHz-300 GHz, Visible light: 400-790 THz, X-rays: 30 PHz-30 EHz.
Q4: How does medium affect wavelength?
A: When waves enter a different medium, the frequency remains constant but the speed changes, resulting in a different wavelength.
Q5: What is the significance of the speed of light constant?
A: The speed of light (c = 299,792,458 m/s) is a fundamental physical constant that represents the maximum speed at which all energy, matter, and information can travel.
