Charged particles emitted by the sun into space?
''Charged particles emitted by the sun'' into space is called solar wind.
What type of energy is received on earth from the sun and other stars?
Heat, visible light, and infrared light (UV Rays) are the three main types of energy emitted from the sun and stars. Although, around 30% of it does get forced back into space.
An astronaut inside a small space ship orbiting around the earth cannot detect gravity.If the space station orbiting around the earth has a large size can he hope to detect gravity?
If the size of the space station is large enough, then the astronaut will detect the change in Earth's gravity (g).
What colors and all colors is the the sun?
The frequency of the light depicts the colour of light we see.The sun emits light on many different frequencies including that of every single colour and also invisible frequencies like ultra-violet, microwave, infra-red etc.When the visible light from the sun is examined, the light peaks at the frequency for yellow meaning the sun emits more yellow than all other colours. But it still emits all these other colours as well. Since the light is not exactly even amongst all colours then it makes the sun not white but yellow. This is why our sun is called a Yellow Dwarf Star.But it is pretty close to being white and if our eyes went and saw it in space without protection it would be so bright that we wouldn't be able to tell whether it was actually white or yellow. We need devices to detect the light for us and properly examine it to be able to tell that it is actually yellow.It is our atmosphere and the angle of the sun in the sky that sometimes makes it more orangey or reddish.
Explain why the sun emits white light although it is yellow in colour?
The sun emits pretty much all frequencies (colors) of light, and it appears white when viewed from space (like in orbit around earth). That energy consists of high frequency (blue and violet) light and low frequency (yellow and red) light as well as the rest of the spectrum in between. What actually happens is that the higher frequency light is much more likely to be scattered in the atmosphere than lower frequency light. Scattering is the term applied to the light when it is absorbed by an air molecule and then re-emitted in a random direction. This means that the violet and blue light is much more scattered than the lower frequencies. And the light that reaches our eyes directly from the sun has had violets, blues and greens "scattered out" of it. The reds, oranges and yellows are the frequencies that we see looking directly at the sun, and this is why it has its characteristic color.
Why is it necessary to detect radiation from space and not just light?
Light is radiation.
How do you watch weather from space?
There are weather sattellites that orbit the Earth that can detect reflected radiation, emitted radiation, or radiation reflected only by water vapour as well as satellites that emit microwave radiation to detect the clouds or precipitation.
Charged particles emitted by the sun into space?
''Charged particles emitted by the sun'' into space is called solar wind.
What actors and actresses appeared in Light in the Yellow Breathing Space - 2012?
The cast of Light in the Yellow Breathing Space - 2012 includes: Kamal Addaraarachchi Kaushalaya Fernando Thusitha Laknath Sathsara Savan
What type of wavefront will emerge from a point source and distant light source?
For a point in space (or from a distant light object), spherical waves are emitted. From a point source on the surface of a liquid, circular waves will come out. In both cases the source will be the focus of the emitted waves.
Why is it always dark in space?
We can only see light from what it's reflected off (planets, objects, the moon, things on Earth), or directly emitted from, such as stars including our sun. Space is a vacuum, and therefore is literally just space, so that space can't be hit by light, and can't reflect it.
Does the color yellow take up space?
I suppose it really depends on your definition. If you are coloring with crayons, then the area that you color with yellow will cover a space on the page. But, it is far more complicated than that. Your yellow crayon essentially absorbs all bandwidths of light except for the yellow bandwidth. It reflects the yellow bandwidth of light. So, yellow is actually just the perception of electromagnetic waves in the visible light spectrum with frequencies between 5.6 x 1014 to 6.1 x 1014 Hertz. So, in a theater, for example, yellow light might be projected from a lamp above (out of view). You may perceive the yellow spot on a background as the reflection of that light. But, the yellow light is actually the beam of light being projected, as well as that being reflected to be seen by the audience. Thus, with the partical-wave duality of light, the light itself essentially does not take up any space.
Is the radio telescope an instrument which measures radiation?
A radio telescope has two basic components, a large radio antenna and a radio receiver. It is used to detect radio-frequency radiation emitted by objects in space.
Can Earth-based telescopes can detect all forms of light?
No. Many frequencies of light are absorbed by the atmosphere, and so Earth-based telescopes can't detect it. That's why space telescopes such as the Hubble are so valuable; they allow us to see in frequencies that we cannot detect here on Earth.
How can invisible in space be detected?
Visible light makes up only a fraction of the total light, our eyes and internal components have a limited range over which hey can detect light. This is known as the visual spectrum. However, electronic devices (sensors) exist that can detect ranges of light our eyes cannot.
In what form is radiant energy reflected back into space?
Energy is re-radiated by the Earth as infrared (thermal) radiation.
How astronauts see in outer space if they are not near a sun reflecting planet or object?
If there is no light, then they don't see anything. They can see light emitted from or reflected off of things like planets, stars or spacecrafts.
