Wavelength of Light Formula:
| From: | To: |
The wavelength of light formula calculates the distance between successive peaks (or troughs) of an electromagnetic wave using the speed of light and frequency. It provides a fundamental relationship in wave physics and optics.
The calculator uses the wavelength formula:
Where:
Explanation: The equation shows the inverse relationship between wavelength and frequency - as frequency increases, wavelength decreases, and vice versa.
Details: Calculating wavelength is crucial for understanding electromagnetic radiation properties, designing optical systems, spectroscopy, telecommunications, and various scientific applications.
Tips: Enter frequency in Hertz (Hz). The value must be valid (frequency > 0). 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, with the speed of light remaining constant.
Q2: What are typical wavelength ranges 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 vacuum?
A: The speed of light in vacuum is a fundamental physical constant (299792458 m/s) and is the maximum speed at which all energy, matter, and information can travel.
Q4: How does wavelength affect light properties?
A: Wavelength determines many light properties including color (for visible light), energy (shorter wavelengths have higher energy), and how light interacts with matter.
Q5: Can this formula be used for all electromagnetic waves?
A: Yes, this formula applies to all electromagnetic waves, from radio waves to gamma rays, as they all travel at the speed of light in vacuum.
