A loud sound is heard at resonance.Why?
A steel wire 2m long whose mass is 3g is under tension of 500 N and is tied down at both ends. Calculate the frequency and wavelength for fundamental mode of vibration.
An organ pipe is tuned to a frequency of 440 Hz when the temperature is 27°C. Find its frequency when the temperature drops to 0°C. Assume both ends of the pipe open.
A wire of diameter 0.04 cm and made of steel of density 8000 kg/m^3 is under constant tension of 80 N. What length of this wire should be plucked to cause it to vibrate with a frequency of 840 Hz?
A piano string has a length of 2.0 m and a density of 800 kg/m^3. When the tension in the string produces a strain of 1%, the fundamental note obtained from the string in transverse vibration is 170 Hz. Calculate the Young's modulus value for the material of string.
A uniform tube 60 cm long stands vertically with its lower end dipping into the water. When the length above the water is 14.8 cm and again it is 48 cm, the tube to a vibrating tuning fork of frequency 512 Hz. Find the lowest frequency to which the tube will resound with it is open at both ends.
A steel wire of length 40 cm and the diameter of 0.25 mm vibrates in unison with a tube, open at both ends and of effective 60 cm when each is surrounding its fundamental notes. The air temperature is 27°C. Find the tension in the wire. Given, the velocity of sound in air at 0°C = 332 m/s and density of steel = 7800 Kg/m^3
A piano string 1.5 m long is made of steel of density 7800 kg/m^3 and young's modulus 2x10^-11 N/m^2. It is maintained at a tension that produced an elastic strain of 1% in the string. Calculate the frequency of transverse vibration of the string when it is vibrating in the second mode of vibration.
An open pipe 30 cm long and a closed pipe 23 cm long, both of the same diameter, each sound their first overtone. If they are in resonance, find the end correction of these pipes.
In a resonance tube experiment, the first and the second resonance positions were observed at 17 cm and 52.6 cm respectively. The tuning fork used was frequency 512 Hz and the temperature was 17°C. Calculate the velocity of sound in air at 0°C and the end correction of the tube.
