Velocity of sound in air is 320m/s. A pipe closed at one end has a length of 1m. Neglecting the end corrections, the air column in the pipe can resonate for sound of frequency : the air column in the pipe can resonate for sound of frequency : Velocity of sound in air is 320m/s. [...]

For a certain organ pipe, three successive resonant frequencies are observed at 425,595 and 765Hz. The speed of sound in air is 340m/s. The pipe is a 595 and 765Hz. The speed of sound in air is 340m/s. The pipe is a For a certain organ pipe three successive resonant frequencies are observed at 425 [...]

An organ pipe closed at one end has fundamental frequency of 500Hz. The maximum number of overtones generated by this pipe which a normal person can hear is An organ pipe closed at one end has fundamental frequency of 500Hz. The maximum number of overtones generated by this pipe which a normal person can hear [...]

The vibrations of four air columns are represented in the adjoining figures. The ratio of frequencies np : nq : nr : ns is The vibrations of four air columns are represented in the adjoining figures. The ratio of frequencies np : nq : nr : ns is October 31, 2020 Category: Cengage NEET by [...]

An air column in a pipe, which is closed at one end, will be in resonance with vibrating tuning fork of frequency 680 Hz. if the length of the column in metre be v = 340 m/s An air column in a pipe which is closed at one end will be in resonance with vibrating [...]

An organ pipe P1 ​closed at one end and vibrating in its first overtone pipe P2 open at booth ends vibrating in its third overtone are in resonance with a given tuning fork. The ratio of the lengths of P1 to that of P2 ​is If the fundamental frequency of closed pipe is 50Hz. the [...]

An open pipe is suddenly closed at one end with the result that the frequency of third harmonic of the closed pipe is formed to be higher by 100 Hz than the fundamental frequency of the open pipe. The fundamental frequency of the open pipe is If the fundamental frequency of closed pipe is 50Hz. [...]

If the fundamental frequency of closed pipe is 50Hz. the frequency of 2nd overtone is If the fundamental frequency of closed pipe is 50Hz. the frequency of 2nd overtone is October 31, 2020 Category: Cengage NEET by C.P Singh , Chapter 17 - Sound Waves , Part 1 ,

65 tuning forks are arranged in order of increasing frequency. Any two successive forks produce 4 beats/s, when sounded together. If the last fork gives an octave of the first, the frequency of the first fork is 65 tuning forks are arranged in order of increasing frequency. Any two successive forks produce 4 beats/s the [...]

When beats are produced by two progressive waves of same amplitude and of nearly same frequencies then the maximum loudness of the resulting sound is n times the loudness of each of the component wave trains. The value of n is 5 beats/sec are produced The frequency of tuning forks A and B are respectively [...]
