We prefer a convex mirror as a rear-view mirror in vehicles because of two reasons - 1. A convex mirror always produces an erect image of the objects. 2. The image formed in a convex mirror is highly diminished or much smaller than the object, due to which a convex mirror gives a wide field of view.

If a trait A exists in 10% of a population of an asexually reproducing species and a trait B exists in 60% of the same population, which trait is likely to have arisen earlier?
Trait B is likely to have arisen earlier because this trait has been replicating and existing in a higher percentage of the population as compared to trait A.

See lessA concave mirror produces three times magnified (enlarged) real image of an object placed at 10 cm in front of it. Where is the image located?
m = − v/u= −3 or v = 3u But u = -10 ∴ v = −30cm.
m = − v/u= −3 or v = 3u
See lessBut u = -10
∴ v = −30cm.
Find the focal length of a convex mirror whose radius of curvature is 32 cm.
R = +32cm and f = R/2= + 32/2= +16cm.
R = +32cm and f = R/2= + 32/2= +16cm.
