# Solution for Explain Why (Or How) In a Sound Wave, a Displacement Node is a Pressure Antinode and Vice Versa, - CBSE (Science) Class 11 - Physics

ConceptReflection of Waves Standing Waves and Normal Modes

#### Question

Explain why (or how) In a sound wave, a displacement node is a pressure antinode and vice versa,

#### Solution 1

In a sound wave, a decrease in displacement i.e., displacement node causes an increase in the pressure there i.e., a pressure antinode is formed. Also, an increase in displacement is due to the decrease in pressure.

#### Solution 2

A node is a point where the amplitude of vibration is the minimum and pressure is the maximum. On the other hand, an antinode is a point where the amplitude of vibration is the maximum and pressure is the minimum.

Therefore, a displacement node is nothing but a pressure antinode, and vice versa

Is there an error in this question or solution?
