Question

exit slip: if you make a sound louder by increasing the amplitude of vibes in the medium?ation, what happens to the density of the compression band

Explanation:

Step1: Understand sound wave properties

Sound is a longitudinal wave. In a longitudinal wave, compression is a region where particles are close together. Amplitude in a sound wave relates to the maximum displacement of particles from their equilibrium position.

Step2: Analyze the effect of amplitude on compression

When the amplitude of the vibration (which causes the sound wave) is increased, the particles in the medium are displaced more from their equilibrium positions. In the compression band (region of high - pressure in a sound wave), more particles are pushed into a smaller volume.
Since density is defined as mass per unit volume ($
ho=\frac{m}{V}$), and if the volume $V$ of the compression band decreases (because more particles are crowded into a smaller space due to larger amplitude) while the mass $m$ (of the particles in that region) increases (more particles are present in that region), the density $
ho$ of the compression band increases.

Answer:

The density of the compression band increases.
