Question
The fundamental frequency of a closed pipe is 220 Hz. If
of the pipe is filled with water, the frequency of the first overtone of the pipe now is
- 220 Hz
- 440 Hz
- 880 Hz
- 1760 Hz
The correct answer is: 880 Hz
Fundamental frequency of closed pipe

If
of the pipe is filled with water then remaining length of air column is 
Now fundamental frequency =
and
First overtone =
fundamental frequency
=
.

An Indian submarine and an enemy submarine move towards each other during maneuvers in motionless water in the Indian ocean. The Indian submarine moves at 50 km/h, and the enemy submarine at 70 km/h. The Indian sub sends out a sonar signal (sound wave in water) at 1000 Hz. Sonar waves travel at 5500 km/h. What is the frequency detected by the Indian submarine
