Wavelength Formula:
| From: | To: |
The wavelength formula calculates the distance between consecutive points of the same phase in a wave. It is a fundamental concept in physics, particularly in wave mechanics and electromagnetic theory.
The calculator uses the wavelength formula:
Where:
Explanation: The formula shows the inverse relationship between wavelength and frequency - as frequency increases, wavelength decreases, and vice versa.
Details: Calculating wavelength is essential in various fields including telecommunications, optics, acoustics, and radio astronomy. It helps determine the properties of electromagnetic waves and their interactions with matter.
Tips: Enter frequency in Hertz (Hz). The value must be greater than 0. The calculator uses the constant speed of light (3×10^8 m/s) for calculations.
Q1: Why is the speed of light constant in the formula?
A: In vacuum, the speed of light is a fundamental constant of nature (approximately 3×10^8 m/s), which doesn't change regardless of the frequency or wavelength.
Q2: Can this formula be used for sound waves?
A: No, this specific formula uses the speed of light. For sound waves, you would use λ = v/f, where v is the speed of sound in the medium.
Q3: What is the relationship between frequency and wavelength?
A: Frequency and wavelength have an inverse relationship. As frequency increases, wavelength decreases, and vice versa, when the wave speed is constant.
Q4: What are typical wavelength values for visible light?
A: Visible light wavelengths range from approximately 380 nm (violet) to 750 nm (red), which corresponds to frequencies of about 400-790 THz.
Q5: How does wavelength affect wave properties?
A: Wavelength determines many wave properties including diffraction patterns, interference effects, and the energy carried by photons in electromagnetic waves.
