Concave mirrors, or curved mirrors, are used as reflecting surfaces in headlights of cars, in telescopes, in satellite dishes, as shaving mirrors, in torches and in solar-powered gadgets. They are also used in electron m... More » Science Physics Optics & Waves

Some real-world examples of Bernoulli's principle are the upward lift exerted upon the wings of airplanes gliders and birds, the upward pressure that enables liquids to be ejected from atomizers, the path taken by a curv... More »

The flickering or twinkling effect of lights when observed from a distance is caused by anomalous refraction as light passes through air, schlieren, where temperatures and densities vary. The technical term for this phen... More »

Convex and concave lenses work through understanding how light interacts with different mediums, specifically glass or glass compounds, and manipulating the medium's shape to achieve some desired magnification effect. Le... More » Science Physics Optics & Waves

The most commonly seen example of a convex mirror is the side view mirror on a car. Convex mirrors are seen in dome mirrors found in offices and stores for security and anti-theft purposes. More » Science Physics Optics & Waves
