¿Cómo viaja el sonido? – ¿Qué sigue?

The video explains how sound travels through air particles and what happens when a vacuum is created. By placing a clock inside a capsule and removing the air, a vacuum is formed, preventing sound from traveling. This demonstrates that without air particles, sound cannot be heard.

How does sound travel through the air?

• By vibrating particles

• By magnetic fields

• By electrical currents

• By light waves

What happens when a clock is placed inside a capsule and the air is removed?

• The clock changes color

• The clock becomes louder

• A vacuum is created

• The clock stops ticking

What is the main effect of creating a vacuum around a sound source?

• Sound becomes louder

• Sound travels faster

• Sound cannot be heard

• Sound changes frequency

Why can't we hear the alarm in a vacuum?

• The alarm is too quiet

• The vacuum absorbs the sound

• There are no particles to carry the sound

• The alarm is broken

What is necessary for sound to travel?

• A vacuum

• Vibrating particles

• A solid object

• A light source
