For the following question, two statements are given- one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes (i), (ii), (iii) and (iv) as given below. i) Both A and R are true and R is correct explanation of the assertion. ii) Both A and R are true but R is not the correct explanation of the assertion. iii) A is true but R is false. iv)A is false but R is true. Assertion: Concave mirrors are used as reflectors in torches, vehicle head-lights and in search lights. Reason: When the object is placed beyond the centre of curvature of a concave mirror, the image formed is real and inverted. please help

The correct option option is;

iii) A is true but R is false

Explanation:

Concave mirrors are used as the reflector in torches, search lights and vehicle-head light because unlike convex mirrors and flat mirrors which spread spread a light away from the light source, concave mirrors reflect the light coming from directions from the light source placed in the mirror's focus towards a collection of parallel beam all directed towards a more or less common focus to aid in seeing far in car head-light and for searching in search light

Therefore, the assertion is true but the reason is not correct as the orientation of reflected light cannot be differentiated and the reason for the use of concave mirrors in the given instances is for enable the visualization of objects in dark areas with aid of the light at the focal point.
