The answer for a rectangular prism would be yes.
PS: I assume that we can discount shining the beam down the length of the prism.
A glass triangular prism is a transparent solid object with a triangular cross-section. It is made of glass and has two triangular bases and three rectangular sides.
The purpose of a glass triangular prism is to refract light. When light enters the prism, it is bent or refracted, which separates the colors of the light into a rainbow effect.
In science, a glass triangular prism is used in experiments and demonstrations to show how light can be refracted. It is also used in spectrometers to analyze the composition of light.
A glass triangular prism has a high refractive index, which means it can bend light at a larger angle than other materials. It is also transparent, and can split white light into its component colors.
The most common type of glass used to make a triangular prism is optical glass, which is a type of glass with specific properties for use in optics. Other types of glass, such as crown glass or flint glass, can also be used to make triangular prisms.
