NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Medium-Class 11
Consider a diagram showing a glass tube partially filled with water, where one end is in contact with water and the other end is open. If the end in contact with water is a node and the open end is an antinode, what is the expression for the possible wavelengths of the stationary waves in the tube?
A
λ = 2L/(n + 0.5), for n = 0, 1, 2, 3, ...
B
λ = 4L/(n + 1), for n = 1, 2, 3, ...
C
λ = L/(2n), for n = 1, 2, 3, ...
D
λ = L/n, for n = 1, 2, 3, ...
Correct Answer
Option A
Detailed Explanation
In a tube with one end closed (node) and one end open (antinode), the possible wavelengths are given by λ = 2L/(n + 0.5) as derived from the boundary conditions described in the NCERT context.
