Question

(a) Draw a diagram to represent a sound wave.
(b) How does sound produced by a source reach our ears?

Answer 1

$$(a)$$ Figure 1 represents the sound wave of Small amplitude
Figure 2 represents the sound wave with high amplitude.
Figure 3 represents the sound wave with high pitch.
Figure 4 represents the sound with low pitch.
$$(b)$$ Sound reaches our ears in the form of transverse waves or vibrations from its source of production.
A vibrating object creates compression and rarefaction of the surrounding air molecules, and those sound pressure waves in the air in turn cause the tympanic membrane in your ears to vibrate.
