Some are and some are not.
If you hear an AM radio station at night from more than a few hundred miles away,
or a "short-wave" station from maybe 100 miles away, chances are very good that
it has reflected from the ionosphere before it reached you.
It's very rare for TV or FM radio to reflect from the ionosphere. That almost never
happens except during periods of high solar activity.
What else can I help you with?
What is the distance between earth and ionosphere?
1000km
What characteristic of the ionosphere enables radio active waves?
The ionosphere has nothing to do with radioactivity, and there is nothing in nature that is called a "radio active wave."Because the ionosphere contains electrical charges, it is able to reflect radio waves.
Radio waves bounce and return to earth?
The Radio waves are reflected back to Earth in the Ionosphere.
What is the ionosphere current?
The ionosphere current refers to the flow of charged particles (such as electrons and ions) in Earth's ionosphere. These currents are influenced by the magnetic field of the Earth and play a crucial role in the interaction between solar radiation and the Earth's atmosphere. Ionospheric currents are important for phenomena like auroras and the propagation of radio waves.
Which is the farthest from earth Troposphere Stratosphere Ionosphere or Mesosphere?
The Ionosphere is the farthest layer from Earth among Troposphere, Stratosphere, Ionosphere, and Mesosphere. It extends from about 48 kilometers (30 miles) to 965 kilometers (600 miles) above the Earth's surface.
What is the name of atmosphere between stratosphere and ionosphere?
The atmosphere between the stratosphere and the ionosphere is called the mesosphere. It is located approximately 31 to 53 miles (50 to 85 kilometers) above the Earth's surface.
Radio communication between distant places on Earth is possible because the?
ionosphere reflects radio signals.
Which Atmospheric layer reflects radio wave?
It is the ionosphere, a general region that includes all of the thermosphere and parts of the two bordering layers. In this region, between 60 and 1000 kilometers above the Earth, ionized particles refract and reflect radio waves back toward the ground. This enables radio transmissions that are normally "line of sight" only to reach over the horizon for hundreds or thousands of miles. This includes broadcast radio (HF) and shortwave bands.
What do radio waves bounce off?
Radio waves are reflected by many solid objects, such as wood, stone, and notably metal, allowing the use of microwaves in radar applications.Also importantly in broadcast radio, the ionosphere (an upper layer of the Earth's atmosphere) can bounce signals back down to locations beyond the line-of-sight horizon.
Does the sunspots affect the earth?
The primary affect on the Earth is on our ionosphere
How far from earth is the ionosphere?
274 kilometers from the earth exactly.
Which layer contains ions?
The ionosphere, which is part of the Earth's atmosphere, contains ions. The ionosphere is located in the thermosphere and is responsible for reflecting radio waves back to Earth and playing a role in the Earth's magnetic field.
