How do concave and conex bend light?
Concave mirrors and lenses converge light rays towards a focal point, causing them to bend inward. In contrast, convex mirrors and lenses diverge light rays, causing them to spread out. This bending of light is due to reflection and refraction at the surface of the mirror or lens.
Difference between concave and convex in the dark?
Concave surfaces are inwardly curved, causing light to be focused towards a single point (e.g., a concave mirror), resulting in a real image. Convex surfaces are outwardly curved, causing light to be spread out or dispersed, resulting in a virtual image. In the dark, a concave surface may appear darker as it focuses light away, while a convex surface may appear lighter as it scatters light.
Which type of mirror causes light to spread out?
A concave mirror causes light to converge to a focal point, while a convex mirror causes light to diverge and spread out.
Do concave lens spread light rays apart?
Yes, concave lenses cause light rays to diverge or spread out. When light rays pass through a concave lens, they are refracted in a way that causes them to spread apart. This results in the formation of virtual images that appear smaller and upright.
Do convex mirrors focus light?
Convex mirrors do not focus light, but instead they diverge the light rays that hit them. This causes the reflected light rays to spread out which results in a wider field of view.
What effects does light have on concave and convex mirrors?
Light interacts with concave and convex mirrors in different ways. Concave mirrors converge light rays to a focal point, creating real or virtual images depending on the object's position relative to the mirror. Convex mirrors diverge light rays, creating smaller, upright, and virtual images, making them useful for wide-angle views or as security mirrors.
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.
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.

How are concave and convex lenses different?
Convex bulges outward (thicker in the center than the edge)Concave bulges inward (thinner in the center than the edge)Convex lenses magnify when you look through then, concave lenses make things look smaller.You can focus a distant object to a point with a convex lens (the image will be upside down).
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.
Are convex mirrors used in projectors?
Yes, convex mirrors are used in projectors to reflect and focus light onto the screen or surface. The curved shape of the convex mirror helps to spread the light rays in a way that helps to create a clearer and larger image.
