NEET Physics (general) MCQ Question
Type: MCQ-numerical-Hard-Class 11
A tube partially filled with water has its closed end at x = 0, which is a node. If the open end at x = L is an antinode, what is the wavelength of the sound wave in terms of L for the first harmonic?
A
λ = 4L
B
λ = 2L
C
λ = L
D
λ = L/2
Correct Answer
Option A
Detailed Explanation
For a tube with one closed end (node) and one open end (antinode), the wavelength for the first harmonic is λ = 4L. This is based on the relation: L = (n + 1/2)λ/2 for n = 0.
