What causes concave nails?
anemia
What are the causes of epidemic?
I can tell you that i think that the causes of cholera epidemic, is all from things that come into our country and many other countrys that may (or may not) be contaminated with this rechad desieas.
What causes light rays passing through it to diverge?
A concave lens causes light rays passing through it to diverge because it is thinner at the center than at the edges. This shape causes the light rays to refract away from the optic axis, resulting in divergence.
Difference between concave and plano concave?
A concave lens has a curved surface that curves inward on both sides, causing light rays to diverge after passing through. In contrast, a plano-concave lens has one flat side and one curved concave side, which also causes light to diverge but with less optical power compared to a fully concave lens.
What does each concave and convex lens cause light rays to do?
A convex lens causes light rays to converge (come together) after passing through it, while a concave lens causes light rays to diverge (spread apart) after passing through it.
What lens has a thinner middle than the edges?
A concave lens has a thinner middle than the edges. This causes light rays passing through the lens to diverge, which is why concave lenses are often used to correct vision problems like nearsightedness.
Are concave lens' thinner in the middle?
Yes, concave lenses are thinner in the middle and thicker at the edges. This shape causes light rays passing through them to diverge, making them useful for correcting nearsightedness.
What is concave lens also called?
A concave lens is also known as a diverging lens because it causes incident light rays to diverge away from a common point known as the focal point.
Which type of mirror causes light to spread out?
A concave mirror causes light to converge to a focal point, while a convex mirror causes light to diverge and spread out.
Do concave lens spread light rays apart?
Yes, concave lenses cause light rays to diverge or spread out. When light rays pass through a concave lens, they are refracted in a way that causes them to spread apart. This results in the formation of virtual images that appear smaller and upright.
What is a Plano-concave lens?
A plano-concave lens is a type of lens that has one flat surface (plano) and one concave surface that curves inward. It causes light rays to diverge after passing through it, making it useful for applications that require spreading out light, such as reducing the intensity of a beam.
Is a lens that is thicker at the edges than in the middle a concave lens?
No, a lens that is thicker at the edges than in the middle is a convex lens. A concave lens is thinner at the center than at the edges.
