- Free and Forced vibrations
undefined video tutorial00:20:23
A sonometer wire vibrates with three nodes and two antinodes, the corresponding mode of vibration is ...................
a) First overtone
b) Second overtone
c) Third overtane
d) Fourth overtone
What are forced vibrations and resonance? Show that only odd harmonics are present in an air column vibrating in a pipe closed at one end.
A stretched wire emits a fundamental note of frequency 256 Hz. Keeping the stretching force constant and reducing the length of wire by 10 cm, the frequency becomes 320 Hz. Calculate the original length ofw'ire.
