Radiation and Propagation of Waves Articles: Fundamentals of Electromagnetic Waves: Fundamentals of Electromagnetic Waves are energy propagated through free space at the velocity of light, which is approximately 300 meters…
Space Waves: Space waves generally behave with merciful simplicity. They travel in (more or less) straight lines! However, since they depend on line-of-sight conditions, space waves are limited in their…
Reflection of Waves: There is much similarity between the reflection of light by a mirror and the reflection of electromagnetic waves by a conducting medium. In both instances the angle…
Fundamentals of Electromagnetic Waves: Fundamentals of Electromagnetic Waves are energy propagated through free space at the velocity of light, which is approximately 300 meters per microsecond. As the object travelled downward,…
