Glossary of terms in optics

A glossary of terms in optics includes key concepts like *refraction*, the bending of light as it passes through different materials; *reflection*, the bouncing of light off surfaces; *lens*, a curved piece of glass that focuses or disperses light; *aperture*, the opening that controls light entry; *focal point*, where light rays converge or appear to diverge; and *magnification*, making objects appear larger. Other terms include *prism* (a glass that disperses light into spectrum), *wavefront* (the surface of light waves), and *diffraction* (light bending around obstacles). These terms help us understand how we see and manipulate light.
