Which of the following musical instruments is not matched with its vibrating part?
A jaltarang is a musical instrument made of a combination of water-filled bowls or glasses. In each bowl, water is filled up to different levels. When the bowls are gently struck in succession by a stick, the air column of each bowl vibrates to produce different frequency sounds. The combined effect is a pleasant sound. Hence, the air column is the vibrating part of the jaltarang.
