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                                                      [AIEEE 2008]

A)  \[54>x>36\]

B)  

C)  

D)       

Correct Answer: D

Solution :

[d]

As velocity of sound increases with temperature, V' > V
