Question

Question 1.
(A) The diagram in figure below shows the displacement time graph of a vibrating body
i) Name the kind of vibration
i) Give one example of such vibrations,
displacement
AAA
As
(B) Two waves A and B are of amplitudes 3cm and 4cm respectively. Compare their loudness.
Which sound is louder ?
(C)
displaceniu
Two sound waves A and B are represented by the above graph. Compare their loudness,
pitch and quality​

Answer 1

Answer:

1) ....not sure....for this yaar .....sorry

B) now as loudness =(amplitude)² so, the the wave B of altitude 4 cm is more louder as compared to that of Wave A

Explanation:

If we talk of pitch quality of A and B then actually pitch determines the shrilness of the sound which largely depends over higher frequency means more no. of vibrations passed in a second, so , according to this I think the loudness could vary but the pitch of A and B would remain almost same
