Why do space telescopes collect more kinds of data then telescopes on earth?
Earth's atmosphere partially blocks or absorbs certain wavelengths of radiation, e.g. UV, gamma rays, X-rays, before they can reach Earth's surface. All these wavelengths contain useful information and a telescope outside (beyond) the atmosphere can make use of them too.
What absorbs most of the sun's harmful ultraviolet rays before they reach earth?
The ozone layer present in the stratospheric region of atmosphere protects us from the harmdul rays of the sun. These are high frequency ultraviolet radiations which can cause some serious problems to living beings.
How much radiation does the atmosphere absorb?
The Earth's atmosphere absorbs different amounts of radiation depending on the wavelength. It absorbs most of the sun's harmful ultraviolet radiation and some infrared radiation, helping to regulate the Earth's temperature. Overall, the atmosphere acts as a protective shield, allowing only a small portion of harmful radiation to reach the Earth's surface.
Does the sun appears reddish as it sets because the sun emits more radiation at longer wavelengths at sunset?
Yes, at sunset the sun's light has to pass through more of the Earth's atmosphere, which scatters shorter wavelengths of light, leaving mostly longer, reddish wavelengths to reach our eyes. This is why the sun appears reddish as it sets.
What is the type of uv radiation does not reach the earth?
UVC radiation, which has wavelengths between 100 and 280 nanometers, does not reach the Earth's surface because it is absorbed by the ozone layer in the atmosphere. This type of UV radiation is the most harmful to living organisms, but the ozone effectively protects us from its damaging effects. Therefore, while UVA and UVB rays can penetrate the atmosphere and reach the Earth, UVC is completely filtered out.

Why cant all the wavelengths enter the earth's atmosphere?
The Earth's atmosphere acts like a filter, allowing certain wavelengths of light to pass through while absorbing or reflecting others. Wavelengths such as ultraviolet and X-ray radiation are absorbed by gases like ozone and oxygen in the atmosphere, protecting life on Earth from harmful radiation. This selective filtering ensures that only specific wavelengths necessary for life and the environment reach the Earth's surface.
The Earth's atmosphere filters out certain wavelengths of the electromagnetic spectrum?
Yes, Earth's atmosphere filters out certain wavelengths of the electromagnetic spectrum, such as most ultraviolet radiation and some infrared radiation, before they reach the surface. This filtering is important for protecting life on Earth from harmful radiation.
How does sunlight come to earth?
Electromagnetic energy from the Sun crosses the interplanetary void in about 8 minutes to reach Earth. The energy reaches us as electromagnetic radiation in a very wide range of wavelengths. Some of these wavelengths can be sensed directly by humans as heat and light. Some wavelengths (frequencies) are transformed by interaction with matter into other wavelengths that interact with the hydrosphere, biosphere, etc. to make life on Earth possible.

How does light determine an objects's color?
Light determine an object's by the wavelength of light that reach to your eyes.light can reach your eyes after being reflected by an object,transmitted through an object,or emitted by an object.When your eyes receive the light,they send signals to your brain.Your brain interprets the signals as colors.

What does the earth's atmosphere do to most types of electromagnetic radiation?
The Earth's atmosphere absorbs and scatters most types of electromagnetic radiation, filtering out harmful ultraviolet (UV) radiation from the sun and allowing visible light and some infrared radiation to reach the surface. This natural filtering process helps protect life on Earth by regulating the amount of radiation that penetrates the atmosphere.
Does the sun appears reddish as it sets because the sun emits more radiation at longer wavelengths at sunset?
Yes, at sunset the sun's light has to pass through more of the Earth's atmosphere, which scatters shorter wavelengths of light, leaving mostly longer, reddish wavelengths to reach our eyes. This is why the sun appears reddish as it sets.
Why would gamma rays and light waves reach the earth at the same time?
Gamma rays and light waves can reach Earth at the same time if they are emitted simultaneously from the same event, such as a supernova explosion. Since both travel at the speed of light in a vacuum, they can arrive on Earth together, despite having different properties and wavelengths.
Why black body absorbs heat?
Objects appear white when they reflect all wavelengths of visible light. Reflection of various wavelengths of light means that they are scattering the light back into the space surrounding the object, rather than absorbing that energy.Objects appear black when they absorb all wavelengths of visible light, thus absorbing that energy (some of which is converted to heat).
Why does a meteroid not reach earth?
Burns up before entering the Earths atmosphere
