What do telescopes do with electromagnetic radiation?
Telescopes collect and focus electromagnetic radiation, such as visible light or radio waves, to create images of objects in space. Different telescopes are designed to detect specific wavelengths of radiation to study various astronomical phenomena, from stars and planets to galaxies and black holes.
What is long-wave electromagnetic radiations used in special telescopes?
Long-wave electromagnetic radiation used in special telescopes includes infrared radiation and submillimeter radiation. These telescopes are designed to detect and study objects that emit or reflect these longer wavelengths of light, allowing astronomers to observe phenomena such as cool stars, cosmic dust, and molecular clouds.
How do telescopes and the electromagnetic spectrum work together to help us explore space?
Telescopes are used to observe and magnify images in outer space. The electromagnetic spectrum consists of many wavelengths, which constitute visible light, infrared, microwave, and X-ray radiation. Telescopes can be manufactured to view these certain types of radiation.
How is a radio telescope similar to a refracting telescope and a reflecting telescope?
Radio telescopes, refracting telescopes, and reflecting telescopes all use mirrors or lenses to collect and focus incoming electromagnetic radiation. The main difference is the wavelength of the radiation they are designed to study – radio telescopes focus on radio waves, refracting telescopes focus on visible light, and reflecting telescopes focus on a variety of wavelengths including visible light, ultraviolet, and infrared.
Does the atmosphere block the earth from receiving electromagnetic radiation?
The Earth's atmosphere does not completely block electromagnetic radiation; it selectively absorbs and scatters different wavelengths. For instance, it effectively filters out harmful ultraviolet (UV) radiation while allowing visible light to pass through. Certain atmospheric gases, like ozone, play a crucial role in protecting the surface from excessive radiation. However, some longer wavelengths, such as radio waves, can penetrate the atmosphere more easily.

Different telescopes are designed to detect specific wavelengths of radiation to study various astronomical phenomena, from stars and planets to galaxies and black holes.
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.

Long-wave electromagnetic radiation used in special telescopes includes infrared radiation and submillimeter radiation. These telescopes are designed to detect and study objects that emit or reflect these longer wavelengths of light, allowing astronomers to observe phenomena such as cool stars, cosmic dust, and molecular clouds.
Why do some telescopes that collect electromagnetic radiation in the shorter wavelengths such as ultraviolet or gamma rays need to be placed either in dry areas or outside the atmosphere?
The atmosphere tends to block many of those frequencies. (It's not so much dry, it's as high as possible.)
Why can infrared telescopes operate from high flying aircraft and high mountain tops whereas Xray telescopes must be place in orbit?
Current telescopes detect different wavelengths of "light," which, in general, is called electromagnetic radiation. Earth's atmosphere is transparent to infrared radiation - it can easily transmit though our atmosphere. Therefore we can easily detect it from within Earth's atmosphere. However, X-Rays do not easily transmit through the Earth's atmosphere, so we must place our X-Ray detectors OUTSIDE of our atmosphere, ie. in orbit around the earth.

The what is the arrangement of the forms of electromagnetic radiation according to their wavelengths?
The arrangement of the forms of electromagnetic radiation according to their wavelengths, from shortest to longest, is gamma rays, X-rays, ultraviolet rays, visible light, infrared radiation, microwaves, and radio waves.
What are all the frequencies or wavelengths of electromagnetic radiation called?
The entire range of frequencies or wavelengths of electromagnetic radiation is called the electromagnetic spectrum. It includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each type of radiation has a unique range of frequencies and wavelengths.

Certain atmospheric gases, like ozone, play a crucial role in protecting the surface from excessive radiation. However, some longer wavelengths, such as radio waves, can penetrate the atmosphere more easily.
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.
Why do you not have groundbased gamma ray and x-ray telescopes?
Because radiation at those wavelengths is absorbed in the atmosphere, and very little of it ever reaches the ground. Operated on the ground, those telescopes would see almost nothing.
