Answer 1

1. strings of vina

2. leather surface of tabla

3. the air columns of the flute

4. strings of guitar

5. the metal reeds connected to the frame of harmonium.

6. the vibrating rims of cymbal

1. strings are the vibrating part of vina which vibrate via the saddle & bridge.

2. when the leather surface of the tabla is thumped using our fingers & hands, the sound waves reflect to the leather surface periphery thus producing sound.

3. flute produces sound when a stream of air directed across a hole in the instrument creates a vibration of air at the hole.

4. sound is produced by striking the strings and making them vibrate. The energy of the vibrating strings is transferred to the soundboard through the bridge. The guitar's hollow body amplifies the sound of the vibrating strings. The pitch of the vibrating strings depends partly on the mass, tension, and length of the strings.

5. harmonium produces sound when wind sent by foot-operated bellows through a pressure-equalizing air reservoir causes metal reeds screwed over slots in metal frames to vibrate through the frames with close tolerance.

6. sound is produced by striking one cymbal against the other, thus the rims vibrate but the centre remains motionless.
