Understanding the Structure of a Glass Prism
A glass prism is a transparent optical element that refracts light. To comprehend its structure, let's analyze its surfaces.
Key Components of a Glass Prism
- Triangular Bases: A standard glass prism has two triangular bases. These bases are the top and bottom surfaces of the prism.
- Rectangular Lateral Surfaces: In addition to the triangular bases, a prism has three rectangular lateral surfaces that connect the corresponding sides of the triangular bases.
Total Number of Surfaces
- Counting Surfaces:
- 2 triangular surfaces (the bases)
- 3 rectangular surfaces (the sides connecting the bases)
Thus, the total number of surfaces is 5 (2 triangular + 3 rectangular).
Conclusion
Given the options provided:
- a) Six rectangular surfaces – Incorrect, as there are not six rectangular surfaces.
- b) Four rectangular surfaces – Incorrect, as there are three rectangular surfaces.
- c) Two triangular bases and their rectangular surfaces – Correct, since it accurately describes the structure of a prism.
- d) None of these – Incorrect, as option c is correct.
In summary, option 'C' accurately reflects that a glass prism consists of two triangular bases and three rectangular lateral surfaces, making it the right choice. Always remember that understanding the basic geometry of shapes enhances our grasp of their properties and functions.
