A two ends open cylinder has frequency f in air. On immersing the cylinder in water such that its half length is inside the water, calculate the fundamental frequency of it.

A hollow cylinder with both side open generales a frequency 'f' in air. When the cylinder vertically immersed into water by half its length the frequency will be

If the length of a closed and open pipe is same then what will be the ratio of the fundamental frequencies______.

One mouth of an open pipe is suddenly closed. If is found that the frequency of the third harmonic of the closed pipe is greater by 100 Hz than the frequency of the fundamental of the open pipe. Calculate the funda-mental frequancy of the open pipe.

If a concave mirror is immersed in water will its focal length change?

One end of an open pipe is suddenly closed. It is observed that the frequency of the 3rd harmonic from the closed pipe is 100 Hz higher than the fundamental frequency of the open pipe. Find out this fundamental frequency when both the ends are open .

A hollow pipe of length 0. 8 m is closed at one end. At its open end a 0 . 5 m long uniform string is vibrating in its second harmonic and it resonates with the fundamental frequency of the pipe. It the tension in the wire is 50 N and the speed of sound is 320 m* s^(-1) . the mass of the string is
