Concave is thinner in the center than the edges and convex lens is thicker in the center than on the edges :)
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.
A convex shape curves outward like a bowl, while a concave shape curves inward like a cave. Convex shapes do not make things upside down.
A magnifying lens is typically a convex lens. This type of lens is thicker in the center than at the edges, causing light rays to converge in a way that magnifies objects when viewed through the lens.
Concave lenses make objects look smaller when they are placed close to the lens, while convex lenses make objects look smaller when they are placed far from the lens. This effect is due to the way light rays are refracted by the different lens shapes, causing the image to appear reduced in size.
the lenses make objects look smaller than what they are so that people know what they look like.
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).
Yeah ,for aiming purpose that is for taking target ,but to make gun out of lenses ,it is impossible.
Astronomical telescopes use a large concave mirror, a plane mirror, and a convex lens in their design. The concave mirror gathers light, the plane mirror reflects it to a more convenient viewing location, and the convex lens magnifies and focuses the image for observation.
b. Each convex lens bends light to make the object appear larger. The convex lens in a light microscope refracts and converges light rays to magnify the specimen being observed. By bending light, the lens creates an enlarged virtual image of the specimen that can be viewed by the observer.
A magnifying lens, also known as a convex lens, can make objects look bigger by bending light rays to converge at a point, creating a larger image. This type of lens is commonly used in magnifying glasses, microscopes, and telescopes to achieve magnification.
Answer #1convex lens is something they put in your eyes as contacts or in your glasses if you farsited but convex lens makes your image bigger and concave lens makes your image smaller.Answer #2For example, mirrors can be convex, concave and straight, just like glass. The normal mirrors that you use to look at yourself are straight mirrors, they show a normal picture.Do you ever walk into a shop and see a huge bulging mirror in the corner of the shop and you can see just about every corner of the shop in the mirror? well that is a convex mirror. The curved mirrors show a wider view of everything.The concave mirrors are opposite, they "magnify" the image, the concave mirrors make objects larger because the light is focused on a smaller reflection area.This is exactly what happens if you look through glass, that is either a convex or concave.People who are short sighted have glasses with a concavelens, (the lens that indents, you can also remember that it is concave that way because a cave goes in and a concave lens goes in.People who are long sighted wear glasses with convexlenses.
A lense which bulges outwards is a convex lense.Additionally, a lense which bulges in is called a concave lense. You can remember the difference by thinking about the fact that a cave is like an inward bulge in a cliff, and the inward-bulging lenses are concave.
