Question

Consider the following sounds: G -conversation between two girls, P-sound produced by a peacock and M-sound produced by a moving motorcycle. These sounds in the increasing order of frequency are

• A. G, P, M
• B. P, M, G
• C. P, G, M
• D. M, G, P

Answer 1

Answer: (D)

M, G, P

The Pitch of sound depends on the frequency. We know that the sound produced by a motorcycle has the lowest pitch and the sound produced by a peacock has the highest pitch.

Thus the arrangement in the increasing order of frequency is -

$\text{Motor Cycle}<\text{Conversation between two girls}<\text{Peacock}$

$\therefore M,G,P$
