The ionosphere is more reflective at night because the absence of solar radiation allows for a higher concentration of ionized particles, particularly in the E and F regions. During the day, solar ultraviolet radiation ionizes the atmosphere, leading to a lower density of free electrons in certain layers. At night, the recombination of ions and electrons slows down, resulting in an increased density of reflective ions, which enhances the ionosphere's ability to reflect radio waves. This increased reflectivity can improve long-distance radio communication at night.
What else can I help you with?
What is the effect of the ionosphere increasin its height at night?
When the ionosphere increases its height at night, radio wave propagation improves as higher frequencies are able to reflect off the ionosphere back to Earth. This can enhance long-distance communication, making it easier for radio signals to travel over longer distances during nighttime hours.
Does the temperature increases rapidly after ionosphere?
ionosphere
Why ionosphere is important?
the ionosphere is important is the it is in the thermosphere
What is another name for ionosphere?
Another name for the ionosphere is the thermosphere.
What is the other name for ionosphere?
The other name for ionosphere is thermosphere.
What reflects radio waves at night?
Ionosphere
What is reflective bike tires?
There are some bicycle tires that have a reflective strip around the side wall. This help the cyclist be more visible at night.
How can I enhance the visibility of my clothes at night by incorporating reflective tape?
To enhance the visibility of your clothes at night, you can incorporate reflective tape by sewing or sticking it onto your clothing. Reflective tape reflects light, making you more visible in low-light conditions. This can help increase your safety when walking or biking at night.
Why can some am broadcasts be heard for great distances under certain conditions?
AM radio waves bounce off the ionosphere. Favorable weather conditions and lack of sunspot activity enhance the waves' ability to bounce between the earth's surface and atmosphere, allowing the broadcast to travel a greater distance.
What is the layer of atmosphere where radio signals are reflected back to the earths surface?
The ionosphere bends radio waves . . . most go out into space, but a fair number hit the earth far away, and are reflected back up to the ionosphere. Radio operators call this phenomenon, "The skip".
What layer moves higher at night and lower in the day?
Ionosphere
What material will make you visible at night?
reflective gear such as reflective jackets ECT.
Why can you only listen to am radio stations in a city near you but at night from a distant city?
...AM stations transmit hundreds of miles at night. This extended transmission is possible is because of the ionosphere -- one of the layers of the atmosphere. It is called the ionosphere because when the http://wiki.answers.com/sun.htmrays hit this layer, many of the http://wiki.answers.com/atom.htmthere lose electrons and turn into ions.As it turns out, the ionosphere reflects certain frequencies of radio waves. So the waves bounce between the ground and the ionosphere and make their way around the planet. The composition of the ionosphere at night is different than during the day because of the presence or absence of the sun. You can pick up some radio stations better at night because the reflection characteristics of the ionosphere are better at night.­
Why do coyotes have great vision at night?
they have reflective mirror like tissues at the back of there eye, catches more light. But at night, they usually move by smell, not sight
Why does the range of radio waves increase at night?
If you mean short waves, the answer is that the lower layer of the ionosphere (D layer) dissapears at night so short wave signals then bounce off a higher layer (F1 or F2) of the ionosphere and can travel further.
Besides using reflective tape, what else can help make a child more visible at night while wearing a Halloween costume?
Halloween safety is very important for children. Make them more visible at night with reflective tape, flash lights, and glow sticks that can be worn around the neck. There are also glow in the dark costumes and treat bags that can help others see your child at night.
Why might solar activity cause telegraph wires to short out?
Solar activity will not cause telegraph wires to short out. Wireless telegraphy on the other hand is effected by solar flares hitting the ionosphere. It scatters the reflective wave that long range transmitters use for skip transmissions off of the ionosphere.
