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
