How does a surface wave form?Surface Waves:Surface waves are a type of seismic wave that travels along the space where two different media/substances meet, such as water and air or rock and air. For example, the waves seen at the surface of a lake or ocean are a type of surface wave...

The eardrum has a surface area of approximately 55 square millimeters, while the faceplate of the stapes has a surface area of about 3.2 square millimeters. Sound waves apply force to every square inch of the eardrum, and the eardrum transfers all this energy to the stapes. When you concentra...

And on this glorious day, at that precious moment, regardless of their birth nation, everyone waves the Red, White, and Blue. 即使没有这样的鼓励,其他一些不太容易被人察觉的原因也会让人有理由对这张照片多看几眼。人们可以争辩说,时代广场那个被定格的瞬间标志着美国叙事手法的高潮:美国打败了恶魔...
A 555 timer is a very versatile chip. It can easily create square waves when in astable mode of operation. This circuit utilizes that principle, that 555 timers can easily generate square wave signals. The potentiometers allow us to vary the frequency of the output signal as well as...
These waves are fairly complex, but you can imagine them as similar to waves on water. They have peaks and troughs, and they travel in a straight line until they encounter an obstacle. Obstacles can absorb or reflect light, and most objects do some of both. Reflections from completely smoo...
Also, if you think about it, their rounded-off square waves are delivering more power to the appliance overall than a pure sine wave (there's more area under a square than a curve). This makes them less efficient and the wasted power, dissipated as heat, means there's some risk of ...
