While performing an experiment on verifying the laws of reflection of sound, a students is to choose between
(i) a narrow or a wide tube, and (ii) is strong or a faint source of sound. The observed experimental difference, between the values of angle of incidence and angle of reflection, is likely to be minimum when he chooses a:
A. narrow tube and a faint source
B. wide tube and a faint source
C. narrow tube and a strong source
D. wide tube and a strong source
