Sound reflection & controversy in ray diagram of concave mirror

  1. Dec 12, 2009 #1
    I've two questions here:-
    1) Sound reflects it is said using laws of reflection of light.So,it means we hear max. sound when angle of incidence is equal to angle of reflection,right?& if not equal then what do we hear or not?
    I guess we hear lesser than max.sound when the angles are not equal.

    2) Well,I've drawn ray diagram for concave mirror keeping object exactly at center of curvature according to book the image should form at the same point i.e center of curvature.But it won't, i've tried many times & quite seriously but doesn't forms image at the center of curvature.The image forms ahead of the object but closer but not exactly at the point.
    What's this am i wrong somewhere.Do help me.

    You are appreciated for your reply.
    Thanks in advance.
