Can you see sound vibrations?

Salt Vibrations: Sounds You Can SEE! It's easy enough to tell kids that sounds are caused by vibrations, but that can be a tough concept for them to really grasp! Here are two simple demonstrations that allow kids to actually SEE sound waves in action.

In this manner, how does a vibration become a sound that is heard?

The vibrating body causes the medium (water, air, etc.) around it to vibrate. Vibrations in air are called traveling longitudinal waves, which we can hear. Sound waves consist of areas of high and low pressure called compressions and rarefactions, respectively.

How does vibration affect sound?

Sound waves traveling through the air or other mediums sometimes affect the objects that they encounter. Recall that sound is caused by the molecules of a medium vibrating. Frequency refers to the number of vibrations that an individual particle makes in a specific period of time, usually a second.

What is vibration sound?

In physics, sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain.
