thicker, thinner
Actually, a lens that is thinner in the middle than the edges is a convex lens, not a concave lens. Concave lenses are thicker in the middle and thinner at the edges, while convex lenses bulge out in the middle.
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.
Convex lenses are thicker in the middle than at the edges. They refract toward the center. Only people have convex lenses. Concave lenses are used in telescopes and glasses. Concave lenses are thinner in the middle than at the edges. When light passes through concave lenses always bend away from each other toward the edges of the lens.A convex or "positive" lens is thicker in the middle and thinner at the edges. A concave, or "negative" lens is thinner at the middle and thicker at the edges. Convex lenses project a real image behind the lens; concave lenses project a virtual image in front of the lens.
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).
Concave lenses are thicker at the edges then at the middle. A Convex lens is a lens that is thicker in the center than at its edges.
Convex lens are thicker in the middle. Concave lens are thinner in the middle.
Concave lens. Concave lenses are thinner in the middle and thicker at the edges, causing light rays to diverge. Convex lenses are thicker in the middle and thinner at the edges, causing light rays to converge.
A convex lens.
A convex lens typically fits this description. Convex lenses are thinner in the middle and thicker around the edges, causing light rays passing through them to converge.
Concave and convex lenses both enlarge an object to a certain extend.
A convex lens is a curved lens in which the center is thicker than the edges. Convex lenses are thicker in the middle and thinner at the edges, causing light rays passing through it to converge at a focal point.
Lenses with thick centers and thin edges are called convex lenses. They converge light rays towards a focal point, which allows them to focus light and produce real images.
