The wavelength of light formula calculates the output wavelength when light passes through a medium with a specific refractive index. It demonstrates how light's wavelength changes when moving between different optical media.
The calculator uses the formula:
Where:
Explanation: The formula shows that the wavelength of light in a medium is directly proportional to both the refractive index of the medium and the original photon wavelength.
Details: Calculating wavelength changes is crucial for understanding optical phenomena, designing optical systems, and analyzing light behavior in different materials. It's essential in fields like optics, telecommunications, and spectroscopy.
Tips: Enter the refractive index (must be greater than 0) and photon wavelength in meters (must be greater than 0). The calculator will compute the resulting wavelength of light.
Q1: What is refractive index?
A: Refractive index is a dimensionless quantity that describes how much light is slowed down or refracted when entering a medium compared to its speed in a vacuum.
Q2: How does wavelength change in different media?
A: When light enters a medium with higher refractive index, its wavelength decreases while frequency remains constant. This calculator shows the resulting wavelength.
Q3: What are typical values for refractive index?
A: Vacuum = 1.0, Air ≈ 1.0003, Water ≈ 1.33, Glass ≈ 1.5-1.9, Diamond ≈ 2.42.
Q4: Why is wavelength important in optics?
A: Wavelength determines light's color (visible spectrum), energy, and how it interacts with materials through refraction, diffraction, and interference.
Q5: Can this formula be used for all types of light?
A: Yes, the formula applies to all electromagnetic radiation, though refractive index values vary with wavelength (dispersion).
