Sound comes from vibrations. These vibrations create sound waves which move through mediums such as air and water before reaching our ears. Our ears vibrate in a similar way to the original source of the vibration, allowing us to hear many different sounds. Dogs can hear sound at a higher frequency than humans, allowing them to hear noises that we can’t. Sound is used by many animals to detect danger, warning them of possible attacks before they happen. Sound can’t travel through a vacuum (an area empty of matter). The speed of sound is around 767 miles per hour The loud noise you create by cracking a whip occurs because the tip is moving so fast it breaks the speed of sound! When traveling through water, sound moves around four times faster than when it travels through air. The sound of thunder is produced by rapidly heated air surrounding lightning which expands faster than the speed of sound. Sound waves can be pleasing to the ears. How many of us are lulled to sleep by nice calming sounds. Or jazzed up by fast, loud, pounding rhythms? Sound waves are a form of energy.

First of all Katelyn's comment is really CREEPY. I am not going to be able to sleep. OK back to my comment, I think it is crazy that sound to move faster through water than through air because water is more dense than air. Water is also harder to move in than air.

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
