In the given diagram, a vibrating tuning fork is kept near the mouth of a burette filled with water. The length of the air column is adjusted by opening the tap of the burette. At a length of 5 cm of the air column, a loud sound is heard.
Name the phenomenon illustrated by the above experiment.
Topic: Resonance
Question wording verified against source paper
Answer
Exam answer
Resonance.
Explanation
The air column vibrates with maximum amplitude when driven at its natural frequency.

Equal volumes of water are added to three cylindrical jars A, B and C of same height and radii rA, rB and rC respectively with rB < rA < rC. If you blow air into the mouth of these jars, which tube will produce the shrillest note?
(a) A
(b) B
(c) C
(d) All will produce the notes of same shrillness2026Quality of sound depends on its ............... [amplitude / waveform].2026Define natural vibrations.2026How is this vibration different from damped vibrations in terms of their amplitudes?2026One end of a plastic foot ruler is held tightly at the edge of a table and the other end is plucked. Name the vibrations produced in the ruler.2026Now the ruler is pushed inside partially and plucked again from its free end. State with a reason whether the frequency of vibration increases or decreases.2026
