Brenden Sener creates a miniature model with four mirrors and heat lamp, which proves Archimedes' theory is plausible.

Sener has since earned multiple medals for his attempt to bring the ancient device to life. In his view, he as shown that ...

Digges (or his son Leonard, or both—it isn't clear) used a convex lens and a concave mirror to magnify distant objects, but the shortcomings of such an arrangement were obvious: the observer was ...

Light coming in gets bent and you see a distorted image. Scientists use concave mirrors in large telescopes. On the other hand, convex mirrors are thinner in the middle and bend light outward.

Concave vs Convex Mirror: Know hеrе what is thе diffеrеncе bеtwееn Concave vs Convex Mirror. Concavе mirrors curvе inward and crеatе both rеal and virtual imagеs. Convеx mirrors ...

A mirror image is the result of light rays bounding off a reflective surface. Reflection and refraction are the two main aspects of geometric optics.

Scientists have long debated whether Greek scientist Archimedes could have destroyed enemy ships by redirecting sunlight. Brenden Sener, 13, tested it for a school science fair project.

Plano concave mirror is a mirror which is arrange reflective coating on the concave surface of Optical glass plano concave spherical lens substrates.The diameter, thickness, focal length or radius of ...

Scientists have speculated about how Archimedes’ death ray purportedly harnessed sunlight to burn ships. Now, a teen may have evidence the device was plausible.

COIMBATORE: Motorists expressed concerns as concave mirrors set up by the state highways department on the hairpin bends of Valparai hill road are damaged. Motorists said that concave mirrors are ...
