Based on highresolution air pressure data from both the surface and several measurement sites inside the caves, four systematic changes of pressure waves during their journey through the caves and their related speleoclimatological processes were identified and discussed: Compa...
Sound waves do exactly the same thing, which is why we can hear around corners. Imagine you're sitting in a room off a corridor and, much further up the corridor, there's an identical room where someone is practicing a trumpet inside. Sound waves travel out from the trumpet, spreading ...
Unlike a boat with a v-hull, which rises out of the water and skirts the waves, round-bottom hulls move through the water, making them extremely stable and seaworthy. Passengers on these ships rarely feel any rocking or side-to-side movement. Ships with round-bottom hulls move fluid...
Discover how sound travels from where it originates to where it is heard. Explore the properties of sound waves and how they move through matter,...
So, how exactly do radio waves help weigh the universe? As radio waves travel through intergalactic space, they pass through a lot of stuff but mostly very, very sparse patches of electrically charged gas known as plasma. Because of its electrical charge, the plasma distorts the radio waves...
Interestingly, waves move energy, not water, far distances. Water works as the medium through which kinetic energy, or energy in motion, passes. The water is moving, of course, but only in a circular motion. In other words, water particles work as rollers in a conveyor belt do -- they...
Furthermore, in the air, molecules are distant and it would seem that sound waves have room to travel. In reality, sound is passed from molecule to molecule, and it travels through liquids better than gasses, and through solids better than in liquids. This is because the molecules in a ...
When it comes to propelling an airplane through the sky, different designs depend on different means of propulsion to provide thrust. Most methods, however, work along the same basic principle: An engine accelerates a gas. Let's peek inside a few different engines. Propeller engine: In a typi...
Light waves travel 300,000 kilometers (186,000 miles) per second! They can also travel through a vacuum. That is why light from the sun and distant stars can travel through space to the earth! Soils There are many different kinds of soils. Different soils have different types of rock ...
