A sound source capable of producing sound of variable frequencies is located at a distance of 1 m from a reflecting wall as shown in the figure. A detector D is lying at a point shown in the figure. The various distances are also indicated. If the speed of sound in air is 340" "ms^(-1) , find the frequencies of sound within the audible range, which will have maximum intensity at detector?

Figure shows a tube structure in which a sound signal is sent from one end and is received at the other end. The semicircular part has a radius of 20.0 cm.

A closed organ pipe can vibrate at a minimum frequency of 500 Hz. Find the length of the tube. Speed of sound in air = 340 m s^-1 .

In a closed tube whose length can be altered by sliding one of the halves relative to other is shown in the figure. In the initial condition the dector detects minimum intensity. One of the tubes is then displaced by 5 cm, during this displacement detector detects maximum intensity for 10 times and then a minimum intensity when the displacement is complete. what is the wavelength of sound?

A sound consists of four frequencies : 300 Hz , 600 Hz,1200 Hz and 2400 Hz . A sound 'filter' is made by passing this sound through a bifurcate pipe as shown . The sound wave has to travel a distance of 50 cm more in the right branch - pipe than in the straight pipe. The speed of sound in air is 300 m//s . Then , which of the following frequencies will be almost completely muffled or 'silenced' at the outlet?
