A pipe's lower end is immersed in water ...

A pipe's lower end is immersed in water such that the length of air column from the top open end has a certain length 25 cm. The speed of sound in air is 350 m/s. The air column is found to resonate with a tuning fork of frequency 1750 Hz. By what minimum distance should the pipe be raised in order to make the air column resonate again with the same tuning fork?
(a) 7cm
(b) 5cm
(c) 35cm
(d) 10cm

A
