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 Earth's ozone layer absorbs most of the sun's harmful ultraviolet rays before they reach the surface. This layer is located in the stratosphere and acts as a shield to protect living organisms from the damaging effects of UV radiation.
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 solar blind?
Solar blind refers to a range of ultraviolet (UV) wavelengths that are absorbed by the Earth's atmosphere, making it difficult for these wavelengths to reach the Earth's surface. This provides protection from harmful UV radiation, particularly for living organisms. Solar blind detectors and filters are often used to selectively detect or block UV radiation within this range.

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?
Sunlight travels as electromagnetic radiation through the vacuum of space and reaches Earth by the process of radiation. The Sun emits light in the form of photons which travel at the speed of light and take about 8 minutes to reach Earth.

The Earth's ozone layer absorbs most of the sun's harmful ultraviolet rays before they reach the surface. This layer is located in the stratosphere and acts as a shield to protect living organisms from the damaging effects of UV radiation.
How does light determine an objects's color?
Light determines an object's color based on the wavelengths of light that are reflected off the object. The object absorbs certain wavelengths and reflects others, and the reflected wavelengths are what we perceive as color. Different colors correspond to different wavelengths of light that are reflected.

Overall, the atmosphere acts as a protective shield, allowing only a small portion of harmful radiation to reach the Earth's surface.
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?
A black body absorbs heat because it has a high emissivity, meaning it can efficiently absorb and emit thermal radiation. Its dark color allows it to absorb a wide range of wavelengths of light, converting them into thermal energy. This absorption of heat helps the black body reach thermal equilibrium with its surroundings.
Why does a meteroid not reach earth?
Burns up before entering the Earths atmosphere
