Wavelength Formula:
From: | To: |
The wavelength formula calculates the distance between consecutive crests of a wave. It is a fundamental equation in physics that relates wavelength (λ) to the speed of light (c) and frequency (f).
The calculator uses the wavelength formula:
Where:
Explanation: The formula shows that wavelength is inversely proportional to frequency - higher frequencies result in shorter wavelengths.
Details: Calculating wavelength is essential in various fields including optics, radio communications, acoustics, and quantum mechanics. It helps determine the properties of electromagnetic waves and their interactions with matter.
Tips: Enter frequency in Hertz (Hz) and the 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 standard speed of light value?
A: In vacuum, the speed of light is exactly 299,792,458 m/s, but 3×10^8 m/s is commonly used for calculations.
Q2: How does wavelength change in different media?
A: Wavelength decreases when light enters a medium with a higher refractive index, though frequency remains constant.
Q3: What are typical wavelength ranges?
A: Radio waves can have wavelengths of kilometers, while gamma rays have wavelengths smaller than atoms.
Q4: Can this formula be used for sound waves?
A: Yes, but replace the speed of light with the speed of sound in the specific medium (approximately 343 m/s in air).
Q5: How is wavelength related to energy?
A: For electromagnetic waves, shorter wavelengths correspond to higher energy photons according to E = hc/λ.
