Chapter 1: Geometric Optics

1.1 Introduction Geometric optics is a field of physics that deals with the study of light and its interaction with various media using the principles of geometry. It is based on the assumption that light travels in straight lines called rays, and it simplifies the analysis of complex optical systems by neglecting the wave properties of light. In this chapter, we will explore the basic concepts…

The Wonders of Light: A High School Lesson That Illuminated the World of Optics

Look deep into nature, and then you will understand everything better.– Albert Einstein Unraveling the mysteries of light and its interactions with matter Introduction High school is a time of discovery, where we encounter a vast array of subjects that can leave a lasting impact on our lives. For me, that defining moment came during my sophomore year, when I was introduced to the fascinating…

Icosidodecahedron and truncated icosidodecahedron - with orange and green lines and red and green filters layered on top to filter out one of the solids

That is the drawing with both polyhedra included:

The orange lines depict the icosidodecahedron.

The green lines depict the truncated icosidodecahedron.

Putting a green translucent sheet of foil on top (green filter) filters out the green. The orange stays visible. Hence: With the green filter you mainly see the icosidodecahedron.

Putting a red filter instead filters out the orange and the green stays visible. Hence: With the red filter only the truncated icosidodecahedron is visible.

For drawing the icosidodecahedron I started with drawing a regular dodecahedron and "cut off" the vertices to half of each edge.

For drawing the truncated icosidodecahedron I started with an icosidodecahedron and cut off the vertices to one third of each edge.
