Is this statement false Lenses may be planar convex or concave?
Yes, the statement is false. Lenses may be planar, convex, or concave, but they cannot be both convex and concave at the same time. Each lens can only have one of these shapes.
What are the types of lenses and mirrors?
Lenses: converging (convex) and diverging (concave) Mirrors: concave and convex
Is a lenses in glasses concave or convex?
Lenses can be concave or convex depending on their shape. Concave lenses curve inward and are thinner in the center, causing light to diverge. Convex lenses curve outward and are thicker in the center, causing light to converge. Glasses can have either concave or convex lenses, depending on what vision correction is needed.
How are concave and convex lenses different?
Concave lenses are thinner in the middle and thicker at the edges, causing light rays to diverge when passing through them. Convex lenses are thicker in the middle and thinner at the edges, causing light rays to converge when passing through them. This difference in shape results in different optical properties, with concave lenses causing light to spread out and convex lenses causing light to come together.
If a person is farsighted do they need concave or convex lenses?
A person who is farsighted would need convex lenses to correct their vision. Convex lenses help to converge light rays, bringing the focus point forward onto the retina, which helps in correcting farsightedness.
