Why can AM broadcasts be heard for greater distances under certain conditions?
You can hear AM stations farther away more at night due to a condition known as SKIP, or Skywave Propagation. The propagation of AM radio waves changes drastically from daytime to nighttime. This change in AM radio propagation occurs at sunset due to radical shifts in the ionospheric layers, which persist throughout the night. During daytime hours when ionospheric reflection does not occur to any great degree, AM signals travel principally by conduction over the surface of the earth. A condition known as "groundwave" propagation. Useful daytime AM service is generally limited to a radius of no more than about 100 miles, even for the most powerful stations. However, during nighttime hours the AM signals can travel over hundreds of miles by reflection from the ionosphere, a phenomenon called "skywave" propagation. Basically the AM signal bounces off the ionosphere back to the earth rather than traveling in a direct line. This bounce allows the signal to be heard over vast distances. Amateur radio operators call this talking skip.
What is propagation in science?
Propagation means to multiply by natural means. When humans have infants they are propagating.
What are wave propagation?
Propagation of disturbance suffered by a particle in a medium is called wave propagation Wave Propagation is a term used to estimate the actions and characteristics of a wave of motion either in solids, liquids, gasses, or electrical radio type waves by the environment it is in and what factors affect those waves behaviors.
What types of waves do not require any material medium for their propagation?
electromagnetic waves do not require medium for their propagation. such as radio waves.
What do you mean by rectilinear propagation og light?
Rectilinear propagation of light theory states that light travels in a straight line.
What is the population of SkyWave Mobile Communications?
The population of SkyWave Mobile Communications is 2,011.
What is SkyWave Mobile Communications's population?
SkyWave Mobile Communications's population is 170.
When was SkyWave Mobile Communications created?
SkyWave Mobile Communications was created in 1997.

Does Internet usage have positive effects?
Promoting usage of Internet has somehow disturbed the environment. I permit this preliminary answer to be deleted and answered by this field experts. Below are suggestions: 1. Internet require transoceanic length of undersea cables. 2. Some communications use skywave to transport data. Skywave technology is the mean of long distance light propagation using the reverberation or reflection of electromagnetic wave in ionsphere. These high energy electromagnetic waves may interrupt the stability of ecosystem. 3. More and more telephone line grids or terrestrial wireless stations are erected, causing interferences unknown by human.
When was Propagation - album - created?
Propagation - album - was created in 1994.
What type of propagation is used in telephone communication?
Wave propagation
What is advantager of using this type of propagation?
Using this type of propagation allows for rapid and cost-effective multiplication of plants, ensuring a larger quantity of new plants can be produced within a shorter period of time. It also maintains the genetic characteristics of the parent plant, resulting in consistent quality and performance in the offspring.
What does the term artificial propagation mean?
Propagation carried out by man and not naturally.
What is advantage of using this type of propagation?
propagation is the type of how the plant reproduce
Which is the meaning of propagation?
The act of propagating; continuance or multiplication of the kind by generation or successive production; as, the propagation of animals or plants., The spreading abroad, or extension, of anything; diffusion; dissemination; as, the propagation of sound; the propagation of the gospel.
