A tuning fork sounded close to the mouth of the pipe filled with the water produces increased frequencies as water is filled.
Explanation:
The increase of frequency is due to the more reflection of sound takes place. THis reflection is more because the fork is near to the water surface. As we know with distance and time the intensity of the sound waves decreases.
Frequency of sound is due to the vibration of particles as it is in air and when fork gets nearer to water surface sound intensity increases due to the addition of reflected sound wave from water with original sound wave.
