Wavelength Formula:
| From: | To: |
The wavelength of light formula calculates the distance between consecutive peaks of a light wave using the fundamental relationship between the speed of light, frequency, and wavelength.
The calculator uses the wavelength formula:
Where:
Explanation: This formula demonstrates the inverse relationship between frequency and wavelength - as frequency increases, wavelength decreases, and vice versa.
Details: Calculating wavelength is essential in optics, telecommunications, spectroscopy, and understanding electromagnetic radiation properties. Different wavelengths correspond to different colors in the visible spectrum and different types of radiation in the electromagnetic spectrum.
Tips: Enter frequency in Hertz (Hz). The value must be positive and greater than zero. The calculator will automatically use the speed of light constant (3×10⁸ m/s).
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, while the speed of light remains constant.
Q2: What are typical wavelength values for visible light?
A: Visible light wavelengths range from approximately 380 nm (violet) to 750 nm (red), corresponding to frequencies of about 400-790 THz.
Q3: Why is the speed of light constant in this calculation?
A: The speed of light in vacuum is a fundamental physical constant (approximately 3×10⁸ m/s) that remains the same regardless of the light's frequency or wavelength.
Q4: Can this formula be used for other electromagnetic waves?
A: Yes, this formula applies to all electromagnetic waves, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Q5: How does wavelength affect the color of light?
A: In the visible spectrum, different wavelengths correspond to different colors. Shorter wavelengths appear violet/blue, while longer wavelengths appear red.
