SUMMARY

The discussion focuses on the image formation characteristics of a (45 degrees, 90 degrees, 45 degrees) prism. It establishes that this type of prism can produce either a laterally inverted image or an inverted image, depending on the number of total internal reflections. Specifically, if light rays are reflected by one side of the prism, the image appears laterally inverted, while reflections from two sides result in an inverted image. The orientation of the viewer plays a crucial role in determining the perceived inversion.

PREREQUISITES
  • Understanding of total internal reflection in optics
  • Basic knowledge of prism geometry
  • Familiarity with light ray behavior
  • Concept of image inversion in optics
NEXT STEPS
  • Research the principles of total internal reflection in optical devices
  • Study the geometric properties of prisms, specifically the (45-90-45) prism
  • Explore the concept of image formation in optics
  • Learn about the applications of prisms in optical instruments
USEFUL FOR

Students of physics, optical engineers, and anyone interested in the principles of light behavior and image formation using prisms.

How many kinds of nature of image formed by a (45 degrees,90degrees,45degrees) prism are there...??
Can you tell me all in detail...??thx a lot.. :smile:
 
Science news on Phys.org
I don't quite understand your question, pls explain with detail...
 
um..let's put in this way..
I know the (45' 90' 45')prism will form a laterally inverted image or only a inverted image...
But when will the such condition happen..??
i.e. when will the laterally inverted image form out and also the inverted image..
What elements should be satisfied to form each respectively..?? :smile:
 
i still don't understand your question, but let me do a little bit explanation here, the image is laterally inverted or vertically inverted is depend on the viewer, and how do you define UP/DOWN and LEFT/RIGHT, anyway, the image through a prism will reflected one time, so, either LEFT/RIGHT or UP/DOWN will reverse ONE TIME, and not both...hope this answer your question
 
but the prism has 3 sides..
they will do total internal reflection..


the following is the description of my drawing at home:

I found that if two parallel light rays is total internal reflected by only one side of the prism..the image will be laterally inverted(just like a mirror)

and the other case is that if two parallel light rays is total internal reflected by two sides of the prism together,the image will be inverted..
 
Is it correct ...??
 
yes, u are correct
