Question 1 :
An open pipe of length 24 cm is in resonance with a frequency 660 Hz. The radius of pipe is : (V=330 ms$^{-1}$)<br/><br/>
Question 2 :
An organ pipe $P_1$ closed at one end vibrating in its first overtone and another pipe $P_2$ open at both ends vibrating in its third overtone are in resonance with a given tuning fork. The ratio of lengths of $P_1$ and $P_2$ is
Question 3 :
The fundamental frequency of an open pipe is $\displaystyle n$. If the pipe is vertically immersed in water up to half the length of the pipe, then the fundamental frequency of the air column in the remaining pipe will be
Question 4 :
An organ pipe of length L is open at one end and closed at other end. The wavelengths of the three lowest frequencies that can be produced by this pipe are<br/>
Question 6 :
A closed organ pipe and an open organ pipe of same length produce $2$ beats per sec while vibrating in their fundamental modes. The length of the open organ pipe is halved and that of closed organ pipe is doubled. Then the number of beats produced per second while vibrating in the fundamental mode is
Question 7 :
The fundamental frequency of a closed end organ pipe is $n$. Its length is doubled and radius is halved. Its frequency will become nearly :<br/>
Question 8 :
A steel rod of 100 cm is clamped at its middle. The fundamental frequency of longitudinal vibration of the rod is $2.53k Hz$. The speed of sound in the rod is ____ $ms^{-1}$
Question 9 :
A pipe open at both ends has a fundamental frequency $f$ in air. The pipe is dipped vertically in water so that half of it is in water. The fundamental frequency of the air column is now:<br>
Question 10 :
The velocity of sound in air is $350 m/s$. The fundamental frequency of an open organ pipe of length $50 cm$ will be
