¿Cómo viajan los sonidos?

The video explains how sound travels from singers' mouths to our ears. It describes how vocal cords create vibrations in air molecules, forming compression waves. These sound waves require a medium, such as air, water, or solids, to travel. The speed of sound varies depending on the medium, traveling fastest through solids. Regardless of speed, sound is always transmitted as compression waves.

What happens to air molecules when people sing?

• They become silent.

• They vibrate and create waves.

• They disappear.

• They change color.

Which of the following is NOT a medium through which sound can travel?

• Water

• Vacuum

• Wall

• Air

Why do sound waves need a medium to travel?

• To transmit vibrations.

• To change their frequency.

• To increase their speed.

• To be heard by humans.

In which medium does sound travel the fastest?

• Air

• Water

• Vacuum

• Solid

How is sound always transmitted?

• As electrical signals

• As magnetic fields
