What layer of the atmosphere reflects sound waves?
The thermosphere layer of the atmosphere can reflect certain frequencies of sound waves due to its high temperatures and density of charged particles. This allows for the propagation of long-distance radio communications known as skywave propagation.
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 are the two types of waves according to the direction of propagation?
The two types of waves based on the direction of propagation are transverse waves, where the wave oscillates perpendicular to the direction of propagation, and longitudinal waves, where the wave oscillates parallel to the direction of propagation.
What is the propagation direction of light in a vacuum?
The propagation direction of light in a vacuum is straight and constant.
How does the propagation of light waves in a vacuum relate to the definition of propagation in physics?
The propagation of light waves in a vacuum is the movement of light waves through empty space. In physics, propagation refers to the transmission or spread of waves or energy through a medium. In this context, the propagation of light waves in a vacuum demonstrates the fundamental concept of how waves can travel through space without the need for a material medium.

What signals can bounce off the ionosphere and are sent back to earth?
Radio waves with frequencies below 30 MHz can bounce off the ionosphere and be sent back to Earth. This phenomenon is known as skywave propagation and is commonly used for long-distance communication. The ionosphere reflects these signals back to Earth, allowing them to travel beyond the line of sight.
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.
What type of propagation is used in telephone communication?
Wave propagation
When was Propagation - album - created?
Propagation - album - was created in 1994.
Sky wave antenna?
The term skywave is used to refer to the reflect radio waves from the ionosphere. ?æSkywave is used most frequently in shortwave radio broadcasts.
What is advantage of using this type of propagation?
propagation is the type of how the plant reproduce
