Refract
All lenses refract. You are talking about a diverging lens, which is thinner near the centre than near the rim.
A periscope uses mirrors to reflect light, allowing users to see objects not in direct line of sight.
In complete darkness, devoid of any light -- deep within a cave, for example -- no diamond will 'shine'. Every diamond, however, will reflect and refract ambient light, even if it is simply moonlight or starlight.
No. Diamonds reflect and refract light. Without a light source, a diamond cannot be seen.No, a diamond is not a source of light. A cut diamond appears to sparkle because it is very good at scattering light that strikes it.
The cornea, lens, and iris work together to focus light onto the retina at the back of the eye. The cornea and lens help to bend and refract light, while the iris controls the amount of light entering the eye.
Achromatic means "without color". An achromatic lens is a lens that is virtually free from prismatic color distortions.
a lens will refract light. a mirror will reflect the light.
using an achromatic lens
The achromatic lens was invented by English scientist John Dollond in the 18th century. He developed this lens design to address issues of chromatic aberration in optical instruments like telescopes and microscopes, resulting in improved image quality.

The distracting violet fringing of the image in the telescope was limited by the use of an achromatic lens system.

Point in a chromaticity diagram representing an achromatic color.Achromatic means without color so an achromatic point could be black or white.It is the point at which starch no longer gives a positive result (blue color) to Iodine test.
Hand lenses do not refract light themselves. They allow you to see objects more clearly by magnifying them. Refraction of light occurs when light passes through different mediums with varying densities or refractive indexes.
A concave lens is a lens that is thinner at the center than at the edges. It causes light rays to spread out, diverging as they pass through the lens. A prism is a transparent optical element with flat, polished surfaces that can refract, reflect, or disperse light.
An achromatic lens is a type of lens designed to minimize chromatic aberration, which causes colors to focus at different points. It is made by combining two different types of glass with varying refractive indexes to reduce this effect. The power of an achromatic lens is related to its ability to focus light without chromatic aberration, while its dispersive power is diminished due to the combination of different glass types.
