Question

1. 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

Answer 1

1. (1)

As temperature increases, frequency increases so it will be more than thrice the length, hence (1)

x > 54
