Top 10 Commonly Confused Words in Optical Engineering

Top 10 Commonly Confused Words in Optical Engineering 1. Refraction vs. Reflection: Understanding the Difference Refraction and reflection are fundamental concepts in optics. While both involve the bending of light, they occur in different scenarios. Refraction refers to the bending of light as it passes through a medium, such as when light enters water. On the other hand, reflection is the bouncing back of light from a surface, like a mirror. Remember, refraction is about bending, while reflection is about bouncing! 2. Convex vs. Concave: Shapes and Their Effects Convex and concave are terms used to describe the shape of lenses or mirrors. A convex shape bulges outward, like the exterior of a sphere. This type of lens or mirror converges light, bringing it to a focal point. In contrast, a concave shape curves inward, like the interior of a sphere. Concave lenses or mirrors diverge light, spreading it out. So, convex converges, and concave diverges! 3. Chromatic Aberration vs. Spherical Aberration: Distortions to be Aware of
