In an open end organ pipe of length ' L ', if the velocity of sound is ' V ', then the fundamental frequency will be (Neglect end correction)

Step-by-step solution

For an open organ pipe with antinodes at both ends, the fundamental standing wave satisfies L = ₁ 2 . The fundamental frequency is f₁ = V ₁ = V 2L . Harmonics occur when L = n _n 2 for n = 1, 2, 3, , yielding f_n = n V 2L = n f₁ . All harmonics are present , as n spans all positive integers. Option A correctly states the fundamental frequency V 2L with all harmonics present.
