Physics Wave and Sound General MCQ (Single Correct)

The effect of making a hole exactly at (1/3 rd ) of the length of the pipe from its closed end is such that

its fundamental frequency is an octave higher than the open pipe of same length

its fundamental frequency is thrice of that before making a hole

the fundamental frequency is 3/2 time of that before making a hole

the fundamental alone is changed while the harmonics expressed as ratio of fundamentals remain the same

Text Solution

Verified by Experts

The correct answer is:

CHECK THE SOLUTION

(b, d)

making hole at length from close end. Pipe start behaving as closed pipe of length

So new fundamental frequency n’ =

original fundamental frequency n = n’ = 3 n

So option B and D are correct
