Statement(A) : Concave mirrors are used in street lights.

Statement(B) : Concave mirrors are used as reflectors in head lights.

(i) Actually convex mirrors are placed behind the lamp of street light to

spread the light to cover large area.

(ii) But in head lights we observe concave mirrors present behind the lamp to increase the range of visibility.

So statement (A) is false but statement (B) is true.
