4.00 €(3.31 € VAT excl.)In stock.-
A triangular optical prism is a transparent optical element, usually made of glass, with a triangular cross-section. It is used to refract (refraction) light and (or) separate it into colors.
Shape: triangular isosceles triangle
Material: optical glass
Surfaces: 2–3 polished optical surfaces through which light passes
Dimensions: length 4 cm width 2 cm
How does it work?When white light enters a prism:
It refracts (changes direction) when passing from air to glass.
Light of different wavelengths refracts differently.
As a result, dispersion occurs - white light is separated into a spectrum of colors (rainbow).
USES
Spectroscopy – analysis of light by spectrum
Optical instruments – microscopes, telescopes, binoculars
Laser technology
Education – for demonstrations in physics classes
The decomposition of light in a triangular prism was first studied in detail by Isaac Newton in the 17th century, showing that white light is made up of different colors.
