Sound can travel in vacuum.a)Trueb)FalseCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Sound waves are travelling vibrations of particles in media such as air, water or metal. ... So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.
So answer is false .

Answer

Sound waves cannot travelthrough a vacuum. They need a physical medium to travelthrough. This is because, they propagate mechanically by moving material particles.Vacuum is defined as a space which contains no matter

Answer

Introduction:
Sound is a mechanical wave that requires a medium to travel through. It cannot travel through a vacuum, which is a space devoid of matter. Therefore, the correct answer is option 'b' - False.

Explanation:
1. Sound Waves:
- Sound is a form of energy that travels in the form of waves.
- These waves are generated by vibrating objects, such as a guitar string or vocal cords.
- When an object vibrates, it creates a disturbance in the surrounding medium, causing particles to oscillate back and forth.

2. Medium for Sound Propagation:
- Sound waves require a medium to propagate, which can be a solid, liquid, or gas.
- In a solid, such as a metal rod, sound waves can travel by causing the particles in the solid to vibrate and pass on the energy.
- In a liquid, such as water, sound waves can travel by causing the particles in the liquid to move and transmit the energy.
- In a gas, such as air, sound waves can travel by causing the particles in the gas to compress and rarefy.

3. Absence of Matter in a Vacuum:
- A vacuum is a space devoid of matter, including particles of gas, liquid, or solid.
- In a vacuum, there are no particles to vibrate or transmit the energy of sound waves.
- Therefore, sound cannot propagate through a vacuum as there is no medium for the waves to travel through.

4. Examples:
- In outer space, where there is a vacuum, sound waves cannot travel.
- Astronauts in space cannot hear each other's voices or any other sound because there is no air or other medium to carry the sound waves.

Conclusion:
Sound requires a medium to propagate, and it cannot travel through a vacuum. Therefore, the statement 'Sound can travel in a vacuum' is false.
