Mark the correct choice as: a) If both assertion and reason are true and reason is the correct explanation b) If assertion is true but reason is false. c) If assertion is false but reason is true. 1.Assertion: For observing the traffic at a hairpin bend in mountain paths a plane mirror is preferred over convex mirror and concave mirror. Reason: A convex mirror has a much larger field of view than a plane mirror or a concave mirror.2.Assertion: Incident ray is directed towards the centre of curvature of spherical mirror. After reflection it retraces its path. Reason: Angle of incidencei= Angle of reflectionr= 0o.

"1st answer- correct option “c”
Assertion: For observing the traffic at a hairpin bend in mountain paths a plane mirror is preferred over the convex mirror and concave mirror.
Reason: A convex mirror has a much larger field of view than a plane mirror or a concave mirror.
c) - If Assertion is false but the reason is true.
Second answer- correct option “a”
Assertion: Incident ray is directed towards the centre of curvature of the spherical mirror. After reflection, it retraces its path.
Reason: Angle of incidence I = Angle of reflection r = 00
a) If both assertion and reason are true and the reason is the correct explanation. "
