Answer:− B option
resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at a specific preferential frequency.
so in resonance vibrating bodies have equal frequency.

Q5
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 256Hz. Keeping the stretching force constant and reducing the length of wire by 10cm, the frequency becomes 320Hz. Calculate the original length of wire.
