you already know that light travels much more rapidly than sound. That doesn't mean that sound travels slowly either; at room temperature a sound wave is traveling at over 300 meters per second (more than 1,000 feet per second). The ...

These terms, as well as others used in discussing sound, are best understood through an examination of sound waves and their behavior. Speed of sound in various mediums MediumSpeed in feet per secondSpeed in meters per second Air at 59 degrees F. (15 degrees C) 1,116 340 Aluminum 16,...
Is it a single color or many colors mixed together? Does it have a frequency like sound? And what are some of the common properties of light, such as absorption, reflection, refraction and diffraction? You might think scientists know all the answers, but light continues to surprise them. ...
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 ...
These ionic events occur in many excitable cells besides neurons (like muscle cells). Action potentials are propagated rapidly. Typical neurons conduct at 10 to 100 meters per second. Conduction speed varies with the diameter of the axon (larger = faster) and the presence of myelin (myelinated...
How many minutes must she run? Hint: Use 7.5 mi/h as a conversion factor between distance and time. The speed limit on some interstate highways is roughly 120 km/h. What is this in meters per second? How can someone travel a distance of 41 meters but have a displacement of 0 m...
How Many Mbps Do You Need? Depending on where you live, you may have access to internet connections as fast as 8 Gbps. Do you really need all of that speed? The short answer is probably not. But if you want to figure out exactly how many Mbps you’ll need, you’ll have to think...
