What phenomenon is observed when air is blown into the cap of the pen?...
Phenomenon observed when air is blown into the cap of the pen:
When air is blown into the cap of a pen, a phenomenon known as sound production is observed. This is the correct answer among the given options.
Explanation:
Therefore, the correct answer is option B - Sound is produced.
When air is blown into the cap of a pen, a phenomenon known as sound production is observed. This is the correct answer among the given options.
Explanation:
- How does sound production occur?
- What happens when air is blown into the cap of a pen?
- Why is sound produced in this phenomenon?
- How does the sound reach our ears?
- Why is sound the observed phenomenon?
Sound is produced when there is a disturbance in the air molecules, causing them to vibrate. These vibrations then travel through the air as sound waves, which are detected by our ears.
Blowing air into the cap of a pen creates a disturbance in the air inside the pen. As the air is forced out through the small opening of the cap, it pushes against the surrounding air molecules, causing them to vibrate. These vibrations travel through the air as sound waves.
The sound is produced because the air molecules inside the pen are compressed when blown into the cap. As the compressed air is released, it creates a pressure difference between the inside and outside of the pen. This pressure difference causes the air molecules to move rapidly, resulting in vibrations and the production of sound waves.
The sound waves produced by the vibrating air molecules travel through the air and reach our ears. Our ears detect these sound waves and convert them into electrical signals that are sent to the brain, allowing us to perceive the sound.
Out of the given options, sound is the most relevant phenomenon observed when air is blown into the cap of a pen. The other options, such as light, heat, and chemical energy, are not typically associated with this action and do not occur in this context.
Therefore, the correct answer is option B - Sound is produced.

What phenomenon is observed when air is blown into the cap of the pen?...
When air is blown in the cap of the pen, air molecules vibrate at a frequency corresponding to the resonance of the structure of the pen cap and correspondingly sound is produced.
