Answer 1

Hint: Jal-Tarang is an instrument which is used to produce music. It consists of cups and cups are filled with water to different levels. To produce sound the cups are tapped with a stick or with fingers. This musical instrument produces a very beautiful sound.

Complete answer:
Jal-tarang as the name suggests it is related to water waves. When we hit the cup with a stick or finger, water waves are produced due to vibrations in the cup. These vibrations travel through water in the cups and after striking with the surface of the cup, these vibrations produce sound.
Due to vibrations low pitch and high pitch sounds are produced. If the height of water in the cup is the lowest then lowest pitch voice will be produced. If the height of water in the cup is highest then the highest pitch voice will be produced.
In terms of frequency, we can say that the voice produced will have lowest frequency if the height of water in cup is minimum and the voice produced will have highest frequency if the height of water in cup is maximum.
If the height of water in the cup goes on increasing then both pitch and frequency will increase. If the height of water in the cup goes on decreasing then both pitch and frequency will decrease.
From the above explanation, we can see that all the options given in the question are correct.

So, option (D) is correct.

Note: Jal-Tarang is an ancient Indian musical instrument and it is still in use. This instrument produces a very soothing sound which relaxes our mind. Some other musical instruments have strings to produce sound in other instruments like guitar, veena.
