Question

2. What is fundamental mode of vibration?​

Answer 1

Answer:

Harmonics. The simplest normal mode, where the string vibrates in one loop, is labeled n = 1 and is called the fundamental mode or the first harmonic. The second mode (n = 2), where the string vibrates in two loops, is called the second harmonic. The nth harmonic consists of n vibrating loops.

Answer 2

The lowest part of a harmonic vibration, or the lowest frequency at which an oscillation occurs is called fundamental mode of vibration.

• The basic mode, or first harmonic, is the simplest normal mode, in which the string vibrates in a single loop and is denoted n = 1.
• The second harmonic is the second mode (n = 2), in which the string vibrates in two loops. The nth harmonic is made up of n loops that vibrate.
• In this type fundamental mode of vibration works.
