Question

Read the given statements and select the correct option
Statement 1: The loudness or softness of a sound is determined basically by its amplitude. Statement 2: The amplitude of the sound wave depends upon the force with which an object is made to vibrate.
A. Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
B. Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
C Statement 1 is true but statement 2 is false.
D. Both statements 1 and 2 are false.​

Answer 1

Answer:

B

Explanation:

The amplitude is defined as the magnitude of the maximum disturbance in the medium on either side of the mean value.

The loudness of sound is determined by it's amplitude. So, for a louder sound, it's amplitude must be high. The amplitude of the sound wave depends on the force with which an object is made to vibrate. For example, if we strike the table with less force, a sound which is produced will be of less energy (amplitude). So, we hear a soft sound. But if we strike the table forcefully, higher energy sound wave will be produced and as a result, we hear a loud sound. Thus amplitude is important while controlling and balancing the loudness of sound.
