splitting white light, and turns out refraction is... complicated

Used them - well, actually senses, but the same idea - in a freshman physics lab I taught. They are air filled, and you make the measurements in a water tank. Concave is focusing.Hornbein said:Would it be possible to make a prism with a negative index of refraction?
I read somewhere recently, that is the most widely recognized "logo" worldwide.Frabjous said:I think this is the most popular version![]()

I'm not sure I buy that. There's some stiff competition.gmax137 said:the most widely recognized "logo" worldwide.

A prism is a transparent object with flat, polished surfaces that refract or bend light. It has a triangular shape and is often used to separate white light into its component colors.
Prisms are commonly used in optics and physics experiments to demonstrate the properties of light. They are also used in photography, binoculars, and other optical devices to correct and enhance images.
There are several types of prisms, including equilateral, right angle, and dispersing prisms. Equilateral prisms have three equal sides and are used for dispersing light. Right angle prisms have a 90-degree angle and are used to reflect light at a 90-degree angle. Dispersing prisms have a triangular shape and are used to separate light into different wavelengths.
Prisms can be created by cutting a triangular piece of glass or plastic and polishing the surfaces. They can also be made by pouring a liquid polymer into a triangular mold and allowing it to harden.
Some common examples of prisms in everyday life include rainbows, kaleidoscopes, and the lenses in eyeglasses. They are also used in streetlights, chandeliers, and other decorative lighting fixtures.
