How does a concave lens refract light?Refraction:Refraction is the bending of light as it passes through different materials. There are different lenses that change the way light refracts to help focus images, make images smaller, make images larger, and make images brighter. The eye refracts ...
How does a concave lens correct nearsightedness? Nearsighted people wear glasses with concave lenses to correct their vision. A concave lens corrects myopia by being thinner at the center and thicker at the edge. It diverges light rays entering the eye so they focus a little further back, ...
Photo: A concave lens makes parallel light rays diverge (spread out) so that they appear to come from a point behind the lens—the focal point. The distance from the center of the lens to the focal point is, again, the focal length of the lens. However, in this case, since the ...
Instead of having to draw a driver's blood to test his alcohol level, an officer can test the driver's breath on the spot and instantly know if there is a reason to arrest the driver. Breathalyzers operate so well because they understand how the body processes alcohol. How Much Alcohol ...
