To start with the very basics, here’s a graphic showing how waves work. Wind blows over the ocean surface pushing surface water up into waves. The wind-blown waves will travel on indefinitely until they encounter a shallow bottom surface, which slows down the bottom part of the wave, caus...
thanks to the small size, lack of windows and hanging clothes. If you have to record instruments or voice-over with absolutely zero prep time, use the closet as your best bet. Obviously, you can't do things like record with a drum kit or piano, so this workaround...
There are two types of seismic waves: body waves and surface waves. Body waves include P and S waves, which interact with the surface of the Earth to create surface waves. P waves, or primary waves, are longitudinal waves. P waves move back and forth, like a coiled spring that has bee...
In this article, we'll look at the mechanical systems that make hearing possible. We'll trace the path of a sound, from its original source all the way to your brain, to see how all the parts of the ear work together. When you understand everything they do, it's clear that your ...
In order to have much of a life in the ocean, whales had to be able to swim for long periods of time without coming up for air. To do this, they developed highly specialized respiratory systems. A whale'slungswork the same basic way ours do, but they make the most of each breath....
In this article, we'll walk through the basic principles of aviation and the various forces at work in any given flight. Contents How Do Planes Fly: Thrust and Drag How Do Airplanes Fly: Weight and Lift Aerial Navigation: Wings, Slats and Flaps Aerial Navigation: Stabilizers, Ailerons...
The charging device's surface has strips of conductive metal on it. When a device with corresponding electrical contacts touches these strips of metal, electricity flows into the device. For this to work, the device must have the contacts incorporated into its case or a special sleeve that has...
How does a surface wave form? What causes surface waves? How are surface waves different from body waves? How do surface waves travel differently than body waves? How are waves reflected? What are the different types of surface waves? What are examples of surface waves? How are electromagnetic...
You now need to find and be near an AM radio station's transmitting tower (within 1 mile/1.6 kilometer or so) for this to work. Here's what you do: Drive the stake into the ground or find a convenient metal fence post. Strip the insulation off the end of a 10-foot (3-meter) ...
We do know that skateboarding has its roots in surfing. Surfers called it "sidewalk surfing," but no self-respected surfer took it seriously. They skateboarded to improve their technique, especially when the waves weren't good. As a result, all skateboarding moves mimicked riding waves. In...
