Question
Which of the following organs vibrate to produce voice in most animals?
- Mouth
- Vocal cord
- Throat
- Lungs
Hint:
When a body vibrates, it creates a pressure wave, which in turn produces sound. This pressure wave created generates a vibrational motion in the molecules in the nearby medium.
The correct answer is: Vocal cord
Vocal cords vibrate to produce voice in most animals.
- Sound is considered a form of energy/pressure wave created by a vibrating objects.
- The vocal cord is responsible for the production of sound in animals.
- It has a coiled structure and vibrates when air passes through it and produce sound.
- It is present in the throat (pharynx) of the animals.
