The vibrations of a string of length 60 cm fixed at both ends are represented by the equation y=4sin( 15/πx ) cos (96πt) where x and y are in cm and ‘t’ in seconds. the maximum displacement at x = 5 cm is the air column in the pipe can resonate for sound of frequency [...]

Velocity of sound in air is 320m/s. A pipe closed at one end has a length of 1 m. 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. [...]

A tube closed at one end and containing air produces, when excited the fundamental note of frequency 512 Hz. If the tube is open at both ends, the fundamental frequency that can be excited is (in Hz) A tube closed at one end and containing air produces the fundamental frequency that can be excited is [...]

When two waves meet at point their equations are y1 = 2a cos wt and y2 = 3a cos(wt + pie /2). The amplitude of the resultant wave is When two waves meet at point their equations are y1 = 2a cos wt and y2 = 3a cos(wt + pie /2). The amplitude of the [...]

The third overtone of a closed organ pipe is equal to the second harmonic of an open organ pipe. Then the ratio of their lengths is equal to The third overtone of a closed organ pipe is equal to the second harmonic of an open organ pipe. Then the ratio of their lengths is equal [...]

In a resonance column experiment, the first resonance is obtained when the level of the water in tube is 20cm from the open end. Resonance will also be obtained when the water level is at a distance of In a resonance column experiment the first resonance is obtained when the level of the water in [...]
