Homework Help Overview

The discussion revolves around the comparison of diamond and glass as materials for prisms, focusing on their optical properties, particularly refractive indices and light distortion. The original poster seeks clarification on which material would be more effective as a prism for a physics assignment.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the properties of diamond and glass, particularly their refractive indices, and question the implications of these properties on their effectiveness as prisms. The original poster expresses uncertainty about the nature of diamonds and their internal structure, while others clarify the importance of refractive index in determining the quality of a prism.

Discussion Status

The discussion is active, with participants providing insights into the optical properties of both materials. There is a recognition that diamond has a higher refractive index than glass, which may suggest it is a better prism. However, the original poster's concerns about light distortion and internal structure indicate ongoing exploration of the topic.

Contextual Notes

The original poster mentions the need to explain the concepts to someone else, indicating a focus on understanding rather than simply finding a solution. There is also a hint of confusion regarding the nature of diamonds and their optical behavior.

Which makes a better prism??

Homework Statement



Hey guys, I'm helping my girlfriend once again, in physics 101! I'm not used to these "theory" questions...haha

Anyways, the question asks:Which would make a better prism, a diamond or glass?

I guess, I chose glass...because a diamond has a lot of little prisms inside of it(I think)...so, that would defeat the purpose, in my opinion) Also, a diamond distorts light...I don't know...

Need some help, and need to be able to explain it to her, so she can understand it for the final. Make me understand it first, please!

Thanks,
Brad

Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
you're thinking of diamond that is already cut and polished into a certain shape.
prisms use the refraction of light from one medium to the next. the better prism will have a higher refractive index..
 
So, according to you...Diamond is a better prism(2.42) with glass being(1.52)...just found those off of the net.
 
that's right
 
and likely why diamonds cost a lot more than glass, as in where does all the flash and color come from?
