Question

how can u differentiate concave lens from concave mirrors?

Answer 1

1)Concave lense is transparent whereas concave mirrormirror is opaque.
2)concave mirror cause reflection whereas concave lense cause refraction of light.
3)concave mirror forms both real, inverted images of various sizes and virtual, erect and enlarged images whereas a concave lens forms only virtual image.

Answer 2

concave mirror is bent to the outside liketop one & it bends light to one point whereas Concave lenses are thinner at the middle. Rays of light that pass through the lens are spread out . A convex lens is a diverging lens. When parallel rays of light pass through a concave lens the refracted rays diverge so that they appear to come from one point called the principal focus. A convex lens is called converging lens. hope this helps.. MARK IT BEST PLZ
