MHT CET 2026 Physics question

In a pipe closed at one end, air column is vibrating in the fourth overtone so the vibrating air column has 'x' nodes and 'y' antinodes. The values of x and y are respectively

(A)4, 4
(B)4, 5
(C)5, 4
(D)5, 5Correct

Answer: (D)

Solution

A pipe closed at one end has a node at the closed end and an antinode at the open end, and supports only odd harmonics. The fundamental has 1 node and 1 antinode; each higher overtone adds one more node and one more antinode. The first overtone is the 3rd harmonic (2 nodes, 2 antinodes) and the fourth
