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
