Wavelength Formula:
| From: | To: |
The wavelength calculation determines the distance between consecutive crests of a wave, particularly for light waves. It's calculated using the fundamental relationship between the speed of light, frequency, and wavelength.
The calculator uses the wavelength formula:
Where:
Explanation: The wavelength is inversely proportional to the frequency - higher frequency waves have shorter wavelengths, and vice versa.
Details: Calculating wavelength is essential in optics, telecommunications, spectroscopy, and understanding electromagnetic radiation properties. It helps determine the color of visible light and the behavior of different electromagnetic waves.
Tips: Enter the frequency in Hertz (Hz). The frequency must be a positive value greater than zero. The calculator will automatically use the constant speed of light value (3×10^8 m/s).
Q1: Why is the speed of light constant in this calculation?
A: In vacuum, the speed of light is a fundamental physical constant approximately equal to 3×10^8 m/s, which remains unchanged regardless of frequency or wavelength.
Q2: How does wavelength relate to light color?
A: Different wavelengths correspond to different colors in the visible spectrum. Shorter wavelengths appear violet/blue, while longer wavelengths appear red.
Q3: Can this formula be used for other types of waves?
A: Yes, the general formula λ = v/f applies to all waves, where v is the wave velocity. For light, v equals c (speed of light).
Q4: What are typical wavelength values for visible light?
A: Visible light wavelengths range from approximately 380 nm (violet) to 750 nm (red), which is 3.8×10^-7 to 7.5×10^-7 meters.
Q5: How does wavelength affect wave energy?
A: Shorter wavelengths correspond to higher energy photons according to E = hc/λ, where h is Planck's constant.
