Light is refracted and spread out by what?
convex lens
Light rays refracted by a concave lens?
spread out
What is a lens that spreads light apart?
concave spread light and convex collects lght
How are convex and concave lenses different from each other?
Convex lenses are thicker in the middle than at the edges. They cause light rays to converge. Concave lenses are thicker at the edges than they are in the middle. They cause light rays to spread out, or diverge.
Do concave lenses have negative focal length?
Basically because, in a convex mirror, the curvature is the opposite of that of a concave mirror. It's bevaviour is opposite, too: incoming light is spread out, instead of being focussed.
What effects does light have on concave and convex mirrors?
Light has little or no effect on a mirror. The mirrors follow the rule: "the angle of incidence equals the angle of reflection". Concave mirrors concentrate light to a point and convex spread it out.
Light is refracted and spread out by what?
convex lens
Why do reflecting telescopes use con cave mirrors and not convex mirrors?
Convex mirrors spread and not focus light. They do the opposite of concentrating and magnifying. They are the mirror image of what a concave telescope is and does. Pun intended.
Light rays refracted by a concave lens?
spread out
Why are concave mirrors used in flashlights and automobile headlights?
because the reflected light would spread out over a wide area if convex mirrors were used, whereas concave mirrors focus these reflected light rays into a beam, which give flash lights and headlights their unique characteristic.
How are convex lenses and concave lenses the same?
They are not the same. Convex lens bulge outward, and concave lenses go in ward. Convex lenses focus light, and concave lenses spread light out.
What is a lens that spreads light apart?
concave spread light and convex collects lght
What happens to light that passes through a convex lens?
Light travelling through a concave lens will spread out. In most optical systems that use a concave lens, such as a telescope that needs to magnify the focal plane image, this is a desirable effect.
How are convex and concave lenses different from each other?
Convex lenses are thicker in the middle than at the edges. They cause light rays to converge. Concave lenses are thicker at the edges than they are in the middle. They cause light rays to spread out, or diverge.
Why concave mirror is used in search lights?
The concave shape focuses the light into a narrow beam. If the mirror was convex, the light would be spread out - useless for searching into any distance.
What happens to most of the light rays that strike the convex lens?
The, light rays reflect depending on the curature of the concave.
Why a convex mirror and a concave lens can never produce a real image?
Because the light rays spread out & never meet the focal point
