Answer 1

Answer:

Pitch and Frequency

Explanation:

Pitch is that characteristic of sound by which and acute note can be distinguished from a grave note of same loudness.

Answer 2

Frequency of Wave A and Wave B are different.

Wave A has higher frequency as time period is less and Wave B has more frequency as time period is more.

Characteristics of sound waves are as follows:

1) Wavelength: The minimum distance in which a sound wave repeats itself is called its wavelength.

2) Amplitude: The maximum displacement of the particles of the medium from their original undisturbed positions, when a wave passes through the medium is called amplitude of the wave.

3) Time-period: The time required to produce one complete wave or cycle or cycle is called time-period of the wave.

4) Frequency: The number of complete waves or cycles produced in one second is called frequency of the wave.

5) Speed of Wave: The distance travelled by a wave in one second is called velocity of the wave or speed of the wave.
