convex
A convex lens.
A convex lens is thicker in the center than at the edges. A convex lens is like a concave mirror.A concave lens is thinner in the center than at the edges.
Concave lens
Convex.
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.
A convex lens.
They can be either. They will converge if thicker in the middle than edges, and diverge if thinner in the middle than edges.
Converging. Think of burning ants with a magnifying glass. A magnifying glass is thicker in the middle and it makes the sun's light converge on the ants.
Concave is thinner in the center than the edges and convex lens is thicker in the center than on the edges :)
thicker, thinner
A convex lens is thicker in the center than at the edges. A convex lens is like a concave mirror.A concave lens is thinner in the center than at the edges.
Compared to a uniform thickness lense, concave is where the lense is thinner towards the center of the focal point of the lense than at the thicker edge; convex is much like a magnifying glass where the lense is thicker near the center focal point than at the thinner edges.
Concave lens
A lens that is thinner in the middle and thicker at the edges is called a concave 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.
