Maths Visualizing Shapes part 11 (Prisms) CBSE Class 8 Mathematics VIII

TL;DR

Prisms are optical objects that can separate white light into its seven colors, and their shape consists of two congruent triangles as the base and top, along with three parallelogram faces.

Transcript

hello friends this video on visualizing shapes but 11 is brought to you by exam feel calm no more pure from exam it does not talk about prism prism where have you heard of this name yes in physics so in physics we learn that the white light that we see around us that is actually made up of the seven colors of the rainbow and prism is one such optic...

Key Insights

• 🙂 Prisms are optical objects used to separate white light into its component colors.
• 😀 The shape of a prism consists of two congruent triangles as the top and base, along with three parallelogram faces.
• ⚾ Different types of prisms, such as triangular, rectangular, and hexagonal prisms, exist based on the shape of their base.
• 😀 The number of faces in a prism depends on the shape of its base, with triangular prisms having five faces, rectangular prisms having six faces, and hexagonal prisms having eight faces.
• 🙂 Prisms play a crucial role in understanding the spectrum of light and have practical applications in various fields, including physics, optics, and photography.
• 🙂 By passing white light through a prism, it can be dispersed into its individual colors, showcasing the phenomenon of refraction.
• 🔬 Prisms are commonly encountered in science laboratories, particularly in the study of optics and light.

Questions & Answers

Q: What is the main purpose of a prism in physics?

Prisms are used in physics to separate white light into its individual colors, allowing for the study of the spectrum.

Q: How many faces does a triangular prism have?

A triangular prism has a total of five faces, consisting of two congruent triangles as the top and base, along with three parallelograms.

Q: Can you provide an example of a prism with a rectangular base?

Yes, a rectangular prism has a rectangular base and top, with four additional rectangular faces, resulting in a total of six faces.

Q: Why do different prisms have different numbers of faces?

The number of faces in a prism depends on the shape of its base. Different base shapes, such as triangles, rectangles, or hexagons, result in different numbers of total faces.
