Question 2 What questions can you ask about sound?

Generation of sound: Sound is produced by the vibration of an object. When the vibration stops, the object stops making sound.

propagation of sound

When the alarm clock rings, how does the ringtone reach your ears?

If there is no air, can you hear the ringing?

Experiment description: Sound can travel through the air, but not in a vacuum.

Use a trumpet and a candle to demonstrate how sound travels through the air.

When the sound source is not vibrating, the surrounding air is not vibrating either.

When the sound source vibrates, it will cause the surrounding air to vibrate. This vibration will spread through the air, and the sound will be transmitted to a distant place.

Since sound can propagate in the air, guess what: Can sound propagate in liquids and solids?

Experimental investigation: Can liquids transmit sound?

Set the alarm clock to sound after 1 minute → Put it in a plastic bag → Put it into the water → Put the water pipe into the water → Do you hear the alarm sound?

Sound can be transmitted through all gas, liquid, and solid materials as media. These materials as transmission media are often referred to as media for short.

Sound travels through media. Sound cannot travel in a vacuum.

Astronauts can't hear each other directly on the moon. Is there a way for them to talk to each other?

Please guess which medium in which sound propagates the slowest in gases, liquids, and solids?
