This article provides an overview of the arrangement of particles in a solid and how it is determined. The specific arrangement of particles in a solid is crucial in determining its properties and behavior, and it is influenced by factors such as the type of particles, intermolecular forces or chemical bonds, crystallographic considerations, temperature and …

Lightning is a fascinating natural phenomenon that can be both beautiful and deadly. One of the most intriguing aspects of lightning is its extreme heat, which exceeds the temperature of the sun’s surface. In this article, we will explore the reasons behind lightning’s high temperature, and compare it to other natural and man-made phenomena like …
There exists a minimum temperature for fire to survive and ignite, that is if the heat drops below this amount the flames will cease to exist. Without reaching a certain degree of warmth no sparks or embers can be ignited. Nevertheless, the temperature is not set in stone and differs depending on the fuel or …

How Radio Waves Actually Work Radio waves are a type of electromagnetic radiation, which means they are made up of electricity and magnetism. This makes them different from things like sound waves, which are just vibrations in air (or other materials). Radio waves are made by electrons moving back and forth. When the electrons move, …
What is Sonar? Sound Navigation and Ranging, or SONAR, is a technology that helps you explore and chart the sea since sound waves travel farther in water than do radar or light waves. This is also why submarines use sonar instead of radar. Sonar will use sound waves to detect objects in water. A sonar …
Avoiding Traditional Radar Systems Yes, you can actually fly below the radar. Since the earth is round and radar uses radio waves, which travel in a straight line, “flying under the radar” means flying beneath the area that the radar can directly “see.” The curvature of the earth will block incoming radar signal. Because radar …
Before you purchase a laser pointer online, you may find yourself wondering how far the beam can be seen. If you’re not familiar with different aspects of laser technology, this question might not have a clear answer. You may be wondering why do lasers look grainy sometimes and if that’s a bad sign of quality. …
A laser looks grainy to you because of the wave nature of light or interference. Light coming into your eye from a laser does not exhibit speckle. This ‘grainy look’ or what’s referred to scientifically as Speckle occurs because the laser light is temporally coherent and is scattered from a random surface. The random surface …
Radar transmits pulses of radio waves or microwaves that reflect off any object in their path. The reflected waves are detected by the radar receiver, which uses the information to calculate the position, speed, and other characteristics of the object. Radar can be used to detect objects on the ground, in the air, or in …
