List of top Physics Questions on sound asked in BITSAT

The frequency of a sonometer wire is 100Hz. When the weights producing the tension are completely immersed in water, the frequency becomes 80Hz and on immersing the weights in a certain liquid, the frequency becomes 60Hz. The specific gravity of the liquid is
Ten tuning forks are arranged in increasing order of frequency such that any two nearest tuning forks produce 4 beats/s. The highest frequency is twice of the lowest. The possible highest and lowest frequencies (in Hz) are:
The wavelengths of two waves are 50cm and 51cm respectively. If the temperature of the room is 20^∘C, then what will be the number of beats produced per second by these waves, when the speed of sound at 0^∘C is 332m/s?
A tuning fork of frequency 392 Hz resonates with 50 cm length of a string under tension T. If the mass of the string is decreased by 2%, keeping the tension constant, the number of beats heard when the string and the tuning fork are made to vibrate simultaneously is
The fundamental frequency of an open organ pipe is 300 Hz. The first overtone of this pipe has the same frequency as the first overtone of a closed organ pipe. If the speed of sound is 330 m/s, then the length of the closed organ pipe is:
