Question

Can anyone pls explain me What is the difference between convex mirror,concave mirror,convex lens,concave lens and the difference between their values?

Answer 1

convex mirror and concave lens diverge rays so you get imaginary image but just opposite in case of concave mirror and convex lens

Answer 2

${\huge{\underline{\black{\bf{Answer:}}}$

When an object is near a plane mirror, the image is erect, virtual and of the same size at the object. A concave mirror gives a magnified and erect image of a nearby object whereas a convex mirror gives an erect and diminished image. For the rear view mirror in a car.
