Does infrared radiation reach earth?
Much of it is captured by the greenhouse gases, which hold the heat and prevent it escaping into space. As we add more and more greenhouse gases, they are able to hold more heat. This is how we are causing global warming.
What type of radiation is responsible for heating effect in sunlight?
The Sun emits infrared radiation, as well as a broad spectrum of other rays of electromagnetic radiation. It is the infrared band, that just beyond (and just longer in wavelength) what we see as the color red, which reacts with matter to increase its temperature. Infrared from sunlight heats the Earth's surface and atmosphere.
Why is wave with longer wavelength able to travel further?
It is because longer wavelength wave is diffracted by the earth's atmosphere and so can 'cling' to the surface of the earth, whereas shortwave just goes out into space.
Are years getting shorter or longer why?
Yes sometimes it gets longer because the earth has a strange gravitational pull that pulls and pushes from the sun
Do shadows get longer until it reaches its longest point and then it will start getting shorter?
Shadows get shorter as the sun get higher up in the sky and as the sun goes down shadows will get longer so shadows get shorter in the morning and get longer in the afternoon. Also, as the year progresses, the sun's angle in the sky at the same point in each day changes, due to the 23.5 degree tilt of the Earth's axis. In the northern hemisphere, for instance, shadows get longer and longer (again, at the same time of day) until the winter solstice around December 21st, then they start getting shorter and shorter.
What happens to incoming solar radiation after it is reflected off the surface of the earth?
The wavelength is longer. Energy is re-radiated by the Earth as infrared radiation (heat).
Can infrared be generated on earth?
Infrared radiation is emitted by almost everything on Earth because almost everything is a temperature that will emit at that wavelength. Even you are emitting in the infrared.
The wavelengths of thermal infrared emitted by the Earth are?
The Earth emits thermal radiation of a much lower intensity in the infrared rather than visible region . The wavelength of infrared rays is around 10^-6 meter.

Does Jupiter have a shorter or longer year than earth?
longer

Would a year on Neptune be longer or shorter than on earth?
In terms of Earth years, longer.
If a spacecraft is approaching the earth relative to the radio signals it send out the signal received on the earth have?
Shorter wavelength, higher frequency.
In which region of the electromagnetic spectrum is most of the outgoing radiation from earth?
Aside from all the radio signals generated by Man, the Earth radiates primarily in the Infrared portion of the electromagnetic spectrum. This consists of reflected and re-radiated solar heat and 'black body' radiation from the Earth itself. (The reflected radiation includes some components of shorter wavelength such as visible light, but the re-radiated component is essentially all infrared.)
Would a year on neptune be longer or shorter than earth year?
In terms of Earth years, longer.
Why is wave with longer wavelength able to travel further?
It is because longer wavelength wave is diffracted by the earth's atmosphere and so can 'cling' to the surface of the earth, whereas shortwave just goes out into space.
Why is the sky blue and why are sunsets often red?
red is the farthest of all colors Because the wavelength of red is less than the wavelength of blue. Meaning the red wavelength is shorter than the blue one. The shorter it is the farthest and slowest it reach the earth's atmosphere before it dispersed to sky.
