Question

6. Is it necessary that the cross section of a prism be any
particular type of triangle such as an equilateral
triangle? hey gyes plzz answer it...​

Answer 1

Answer:

No, a prism does not have to be an equilateral triangle. ... The shape of the prism exploits this phenomenon to cause the paths of different wavelengths of light to diverge after passing into the prism and then out again. This occurs only when the 1st interface the light passes through is not parallel to the 2nd interface.

Answer 2

Answer:

No, the cross-section of a prism doesn't need to be any particular type of triangle such as an equilateral triangle.

Explanation:

The operating principle of a prism is that light exhibit dispersion in some media (like some glasses or acrylic), meaning different wavelengths of light travel at different speeds, and therefore exhibit different refraction angles for the same incidence angle. The shape of the prism exploits this phenomenon to cause the paths of different wavelengths of light to diverge after passing into the prism and then out again.
