Young’s Double Slit
Description
Named for Thomas Young’s classic proof of the wave theory of light in 1803. While Young’s original experiment used sunlight and calculated the average wavelength to be 550 nm, today using monochromatic and coherent light one can calculate wavelength with the following formula:
In which, λ is the wavelength of the light
d is the separation of the slits
n is the order of maximum observed (for first order n=1)
x is the distance between the bands of light and the central maximum (also called fringe distance)
L is the distance from the slits to the screen centerpoint
These elements may be used to demonstrate Young’s Interference Fringes, Michelson’s Stellar Interferometer (for measuring the separation between double stars) or other applications requiring measurement of the separation between point sources.

Frequently Asked Questions
Yes, all products are fully customizable including materials. Customers can contact the manufacturer with requests.
The wavelength of light is calculated using the formula λ = d * sin(θ), where λ is the wavelength of the light, d is the separation of the slits, and θ is the angle between the central maximum and the first order maximum.
Orders will be shipped within 5-7 business days, but estimated shipping time is not included.
The diameter tolerance for the Young's Double Slit is +/- 3 µm.
The Young's Double Slit is an optical aperture used to demonstrate Young's Interference Fringes, Michelson's Stellar Interferometer, or other applications requiring measurement of the separation between point sources.
