What happens when concave and convex go together?
When concave and convex surfaces come together, they form a lens. The interaction of these two surfaces causes light to either converge (convex lens) or diverge (concave lens), which can be used in various optical devices like cameras, telescopes, and eyeglasses to focus or correct vision.
Difference between convex and concave lens?
The difference between concave and convex is that convex lenses are the type of lens that make images bigger, while concave make images smaller. Still confused, maybe this will help. When you think of concave think of a cave, how you can see a small image at the end of the cave, while convex is the opposite.
Why Describe two ways using convex and concave lenses to form and image that is smaller the the object?
Using a convex lens: When an object is placed between the focal point and the convex lens, the image formed will be virtual, upright, and smaller in size. Using a concave lens: Placing an object further away from the concave lens than its focal point will result in an image that is virtual, upright, and smaller than the object.
What is the difference between the way parallel light rays are affected by a concave mirror and a concave lens?
The difference between the two is that once the light passes through the concave lens it diverges, and the rays are refracted outward, and never meet a focal point. Then there is the parallel light rays that bounce off the curved surface of a concave mirror and then meet a single point ( focal point).
What lens has an object more than two focal lengths from the lens that will have an inverted message?
A diverging lens, such as a concave lens, will produce an inverted image when the object is located more than two focal lengths away from the lens. This is because the diverging lens causes light rays to spread out, resulting in the image being flipped vertically.
List two uses for concave lens?
Both concave and convex lenses are used in glasses; A microscope, like a reflecting telescope, uses a concave mirror, a plane mirror, and a convex lens; A refracting telescope uses two convex lenses to magnify images in the sky; binoculars use concave lenses to improve detail.
How are reflecting and retracting telescopes different?
A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.
What are the two different shapes of a lens?
Convex and concave
Is concave lens thicker than convex lens?
You can't directly compare the two classes of lenses like that.What you can say is:-- The middle of a convex lens is thicker than the edge.-- The middle of a concave lens is thinner than the edge.One way to remember it: The middle of a concave lens is caved in.
What happens when concave and convex go together?

What are two uses for a convex lens?
Concave lenses are used in glasses for people who are near-sighted. Convex lenses are used in glasses for people who are far-sighted.
What are two possibilities for an image formed by an convex lens?
a convex lens is thicker in the center then at the edges. A convex lens acts like a concave mirror, because it focuses rays of light.
Why Describe two ways using convex and concave lenses to form and image that is smaller the the object?
Using a convex lens: When an object is placed between the focal point and the convex lens, the image formed will be virtual, upright, and smaller in size. Using a concave lens: Placing an object further away from the concave lens than its focal point will result in an image that is virtual, upright, and smaller than the object.
What has two lenses called the eyepiece lens and objective lens?
A microscope has two lenses called the eyepiece lens and the objective lens. The objective lens is closest to the object being viewed and magnifies it, while the eyepiece lens further magnifies the image formed by the objective lens for viewing by the observer.
Two uses for concave lenses?

What uses a lens and two mirrors?
Reflecting TelescopeA reflecting telescope uses a lens and two mirrors. The lens is positioned at the eyepiece, and thus the focus, which the two mirrors generated by specifically redirected light. There are two types of reflecting telescopes with one lens and two mirrors, the Newtonian Focus and the Cassegrain Focus.
