What Is a Prism Used For?
In optics, a prism is a transparent optical device with non-parallel surfaces. Prisms are used for their refractive, reflective, and dispersive qualities, but especially in technical fields that observe spectra....
A dispersive prism can be used to break light up into its constituent spectral
colors (the colors of the rainbow). Furthermore, prisms can be used to reflect light,
Many people suppose that the main optical action of a prism is to disperse white
light into its component parts, because that's what Isaac Newton used prisms for ...
The type of prism used in this video is a triangular prism, it is in the *Dispersive
Prisms* category for prisms. The triangular prism is the most widely known type of

Everyday Examples of Prisms. Prisms are mathematically defined as solid
objects with flat sides, identical ends and the same cross section throughout the
Prisms of this kind are used in certain spectroscopes, instruments for analyzing
light and for determining the identity and structure of materials that emit or absorb
Optics. a transparent solid body, often having triangular bases, used for
dispersing light into a spectrum or for reflecting rays of light. 2. Geometry. a solid
Reflecting prisms are used for erecting or otherwise changing the orientation of
an image and make use of total internal reflection instead of refraction.
