MHT CET 2026 Physics question

In case of stationary wave pattern, which of the following statement is CORRECT?

(A)The distance between consecutive antinodes is equal to the wavelength.
(B)In a pipe open at both ends when an air column is vibrated, only even harmonics are present.
(C)When an air column is vibrated in a pipe closed at one endr all harmonics are present.
(D)In the case of a stretched string, when vibrated frequency of the first overtone is same as the second harmonic.Correct

Answer: (D)

Solution

(A) is false: the distance between consecutive antinodes (or nodes) is , not . (B) is false: an open pipe supports all harmonics (, ), both odd and even. (C) is false: a pipe closed at one end supports only odd
