ABOUT THE SOUND PICTURE

With mouth wide open, vibrating air coming up the throat from the vocal chords leaving the open mouth and spreading in all directions. Hi, I am Janice VanCleave, author of 50+ best-selling science experiment books for children ages 4 through high school. I taught science for 27 years and now am creating this science website.   My scream was not staged. The picture was to be of two adult cats, which I was holding. A microsecond before the camera snapped, the two cats dug their claws into my skin as they prepared to leap out of my arms. A picture like this is great for making inferences. Kids could make "guesses" as to why I am screaming. They would be drawing on facts from the photo, such as I look like I am in pain or maybe I am just pretending.

Mechanical Wave Energy

By

energy-transversejpgA mechanical wave is a type of energy that disturbs the medium through which it travels. This means that something physically moves.

Transverse Wave: A type of mechanical wave energy that causes the medium (material) through which is travels to be disturbed. The movement of the medium is in a direction that is perpendicular (at right angle) to the direction of the wave. In other words, if the energy is moving horizontally, the medium is displaced in an up and down direction.

In the diagram, the direction of the medium’s displacement is up and down, and the movement of the energy is horizontal and to the right. Water waves are a typical example of transverse waves, but the energy that moves through the rubbery material of a trampoline provides a more visual model of how the molecules of the medium are displaced.
