Sound Travel Extension Project Online Research How can we explore the effects of different media on sound? Look up the speed of sound in air, in water, and in steel. Make sure that the speeds are all in the same units, such as feet per second. Which one is the fastest? Do you think...
Sound can't travel in a vacuum. The less dense the air, the harder it is for sound to travel. If two sound waves cross over each other, they interfere with one another. This can lead to the sound being cancelled out, amplified, jumbled up or any mess of noise in between....
Before sound can travel, it needs to be created. For this to happen, there needs to be something that can vibrate which will result in the creation of waves. The vocal chords, for example, vibrate every time someone talks. Based on the pitch determines how the vocal chords vibrate. When ...
How do sound waves travel? Sound vibrations travelin a wave pattern, and we call these vibrations sound waves. Sound waves move by vibrating objects and these objects vibrate other surrounding objects, carrying the sound along. What is sound and how does it travel?
