While measuring the speed of sound by performing a resonance column experiment a student gets the first resonance condition at a column length of 18 cm during winter. Repeating the same experiment during summer, she measures the column length to be x cm for the second resonance then -
(A) x > 54
(B) 54 > x > 36
(C) 36 > x > 18
(D) 18 > x
Correct option (A) x > 54
Explanation:
As temperature increases, frequency increases so it will be more than thrice the length, hence (A) x > 54.
