Question

Sound produced by two instruments have different frequencies but the same amplitude. Choose the correct statement.

• A. Their loudness will be same but pitch will be different.
• B. Their pitch will be same but loudness will be different.
• C. Both loudness and pitch will be different for the two sounds.
• D. Both loudness and pitch will be same for the two sounds.

Answer 1

The correct option is A Their loudness will be same but pitch will be different.

Pitch of a sound is determined by its frequency. Hence, sounds of different frequencies will have different pitch or shrillness. As the amplitude of both the sounds are same, they will be equally loud.
