Question

A string of length ℓ is fixed at both ends. It is vibrating in its 3ʳd overtone with maximum amplitude a. The amplitude at a distance ℓ/3 from one end is:

• A. \(a\)
• B. \(0\)
• C. \(\dfrac{\sqrt{3}a}{2}\)
• D. (a)/(2)

Hint:

For a string fixed at both ends: n-th overtone = (n+1)th harmonic Always write the correct wave equation.

Answer 1

The Correct Option is C
