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.
Does mechinal waves have radio waves?
no, mechanical waves are not radio waves
In which atmosphere layer contains electrically charged particles that reflect radio waves?
The ionosphere - specifically the e-layer
How are electromagnetic waves different to radio waves?
Radio waves ARE electromagnetic waves.
What system locates an object with radio waves and measures the time taken for the waves to bounce back.?
The system that locates an object using radio waves and measures the time taken for the waves to bounce back is called radar (Radio Detection and Ranging). It emits radio waves that travel to the object and reflect back to the source, allowing the system to calculate the distance based on the time delay. This technology is widely used in various applications, including aviation, meteorology, and traffic monitoring.
What would stealth look like on a F-16 Fighter Falcon?
An F-16 isn't stealthy. "Stealth" aircraft are designed to not reflect radar signals back to the transmitter. Since almost all metallic materials will reflect radio waves, they can only be "stealthy" by reflecting the radio waves someplace else other than "back to the transmitter". Stealth aircraft avoid vertical fins and flat surfaces; the rounded surfaces and angled fins are designed to reflect the radar waves up into space, or down to the ground.
Does lead block radio waves?
Yes, lead can block radio waves because it is a dense material that can absorb and reflect electromagnetic radiation, including radio waves.
Why do surfaces reflect light?
Surfaces reflect light because light waves hit the surface and are absorbed and then re-emitted. When light waves encounter a smooth surface, they reflect in a regular way, creating a clear reflection. Rough surfaces scatter light in different directions, creating a diffused reflection.
What do sound waves reflect?
Sound waves can reflect off of hard surfaces such as walls, floors, and ceilings. When sound waves hit these surfaces, they bounce back towards the source creating echoes or reverberation. Reflection of sound waves plays a significant role in how we perceive and understand auditory information in our environment.
Light is to reflect as sound is to what?
Sound is to echo. Just like light bounces off surfaces to reflect, sound waves can bounce off surfaces and repeat in an echo.
What reflects off the ionosphere?
Radio waves reflect off the ionosphere. The ionosphere is composed of ionized particles that can refract and reflect radio waves, allowing for long-distance communication through the atmosphere. The ability of radio waves to bounce off the ionosphere is important for services like shortwave radio and over-the-horizon radar.
What atmosphere contains electrically charged particles that reflect radio waves?
The ozone layer contains electrical charged particles that reflects radio waves
Why do echoes only occur with hard surfaces?
Echoes occur only with hard surfaces because they reflect sound waves effectively. Soft surfaces absorb sound waves, preventing them from bouncing back and creating an echo.
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.
What layer of the atmosphere reflects radio waves?
The ionosphere is the layer of the atmosphere that reflects radio waves. This layer is able to reflect specific frequencies of radio waves back to Earth, allowing for long-distance communication using radio signals.
Why echo is not produced in many places?
Some surfaces reflect sound well, others don't.
Can a mirror reflect sound?
No, mirrors cannot reflect sound as they are designed to reflect light. Sound waves interact differently with surfaces compared to light waves, so while mirrors work for reflecting light, they do not work for reflecting sound.
