Figure below shows the wave patterns of three sounds A, B and C. Name the characteristic of sound which is same between (i) A and B, (ii) B and C, and (iii) C and A.

(i) When we observe the figure shown, we find that both A and B have same amplitude and wave form.

Hence, the characteristics of sound which are same in both A and B are loudness and quality.

(ii) When we observe the figure shown, we find that in B and C, none of the characteristics are same.

(iii) When we observe the figure shown, we find that in both C and A, frequency is same. Hence, pitch is same.
