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 …
Radar is an object detection system that uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircraft, ships, spacecraft, missiles, weather formations, and even animals. Ones that fly and are on the ground. Radar works by sending out a pulse of radio waves and then …
What Are Gamma Rays Gamma rays, like radio waves, infrared radiation, ultraviolet radiation, X-rays, and microwaves, are types of electromagnetic radiation. Electromagnetic radiation is transmitted in waves or particles at various wavelengths and frequencies. The electromagnetic spectrum includes a wide range of wavelengths, which are known as the electromagnetic spectrum. The spectrum is commonly divided …
