I. In a closed organ pipe, standing waves can be formed.

II. In a closed organ pipe (closed at one end), only odd harmonics are present.

III. The harmonics which are present in a pipe, open at both ends are odd harmonics only.

Which of the following statement(s) related to organ pipe is/are correct?

View answer and explanation

Correct option: C

Both I and II

Option C (Both I and II) is correct because closed organ pipes form standing waves and only contain odd harmonics.

The source of sound generating a frequency of

3\,\,kHz

reaches an observer with a speed of

0.5

times, the velocity of sound in air. The frequency heard by the observer is A source of sound emits waves with frequency

f\mathrm{ }Hz

V\mathrm{ }m/sec

. Two observers move away from this source in opposite directions each with a speed

0.2\,\,V

relative to the source. The ratio of frequencies heard by the two observers will be Assertion: The wave function of a pulse is given by

y = \frac{3}{{{{\left( {2x + 3t} \right)}^2} + 4}},

it propagates in

(– \mathrm{ve}) \,x

-direction.
Reason: The given wave function is of the form

y = f(kx +\omega t),

which represent a wave travelling in negative

X

-direction. In the fundamental mode, time taken by the wave to reach the closed end of the air filled pipe is

0.01\,\,s
