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 ...............

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
