Question

Draw a diagram to represent a sound wave.

Answer 1

Hint: A sound wave is a pressure wave or a longitudinal wave. Longitudinal waves are waves in which the particles in the medium in which the wave is propagating travel in the same or opposite directions as the wave. When we study the propagation of a sound wave, the particles in the medium are compressed and stretched by the vibration in the direction of propagation.

Complete Step By Step Answer:
The notion is similar to that of longitudinal wave propagation. As a result, we can claim that the sound wave travels in a straight line.
The frequency of the sound now determines the pitch of the sound. The higher the sound wave's frequency, the higher the pitch note, and the lower the sound wave's frequency, the lower the pitch note.
Loudness of the sound waves are determined by the amplitude. The louder the sound, the greater the amplitude of the sound wave, and the softer the sound, the smaller the amplitude of the sound wave.

The two waves in the diagram above have the same amplitude, and so have the same loudness. However, the two waves have different frequencies. The higher the frequency, the higher the pitch note, and the lower the frequency, the lower the pitch note.

Note:
The high-pitched and loud sounds appeared to be the same. However, they are two distinct quantities with distinct relationships. The pitch of a sound is determined by its frequency, while the loudness of a sound is determined by its amplitude.
