Answer 1

Hint: In this question, we are actually asked the working of Jaltarang, especially what is the most important thing for producing sound of certain frequency. Therefore, we will describe what Jaltarang actually is. We will discuss the construction and working principle of Jaltarang. And therefore, in doing so try to give the key element for producing the sound of certain frequency.

Complete answer:
Jaltarang is a percussion instrument that has its origin in India. Jaltarang consists of a set of bowls that are made from metals or porcelain. They are played using a striker in each hand. The striker is usually a stick made of wood or metal. It is a melodic instrument based on the resonative property of water. When the water is poured in the bowls and struck with the wooden or metal stick it produces vibrations. These vibrations travel in water and are later transferred to the air producing sweet melodies. Jal – tarang literally means waves of water. The frequency is a function of length, therefore, the frequency of the waves can be changed by changing the height of the water. So, to produce the sound of a particular frequency the height of water in bowls is changed.

Therefore, the correct answer is option A.

Note:
Jaltarang is an instrument of Indian origin. This instrument includes a series of bowls laid mostly in a semi-circular pattern, filled with water in different heights. These water levels are tuned to the notes of Raga that are to be played. This instrument requires high skills to be played. An accomplished player can showcase his skills by playing some fine vibrations if he is able to rotate the water in the bowl.
