Why are optical telecopes placed as high as possible?
so that it will not fall down on earth :) and hit someones head! hope it helped
What are the telescopes that work on earth's surface?
X-ray telescopes are used to study mainly the Sun, stars and supernovas. X-ray telescopes work better at very high altitudes on the Earth's surface.
Does a substance having high optical density have to have a high physical density?
It's not necessary. If a compound has high optical density, it means that it absorbs more light at the given wavelength than some reference compound. There is no simple relation between density of matter and optical density. Even more I am pretty sure you can find a lot of compounds with lower densities (of matter) but having high optical density.
Where are most optical telescopes are located?
1. Radio telescopes are directional radio antennae that have a curved shape and are used like other astronomical telescopes to study objects in the universe beyond Earth and the Solar System. They gather radio waves and process them by using a computer.
Why are so many large optical telescopes located on mountaintops?
The reason we locate optical telescopes in high places is because the earth's atmosphere distorts the light that passes through it. If we can get higher up, there will be less atmospheric distortion of the light from the objects we're observing. Additionally, there is usually less light pollution to affect the images, but relief from atmospheric distortion is the primary reason we go up.
Why do optical astronomers place telescopes at the top of mountains while radio astronomers put their telescopes in valleys?
Optical telescopes are placed high to avoid having to look through the thickest part of the atmosphere. Radio telescopes are place in valleys to avoid the effects of man-made electrical noise in the telescope.
Why are big telescopes found on top of mountains?
The Earth's atmosphere provides interference to optical telescopes because the molecules in the air scatter and disrupt light. Many telescopes are placed at high elevation because the atmosphere is thinner and will cause less interference.

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 earth telescopes are on highest places?
They aren't always in the highest places, but it is a great advantage to place them as high above the Earth as possible so the image isn't as distorted by the atmosphere. Siting telescopes at high altitudes enables observations to be made above cloud level. This means you don't have to wait for a sunny day without cloud..
Is it true that a DVD-ROM is a high capacity optical disc?
Yes. Although there are more high capacity disks out there.

What are the advantage and disadvantage of using optical telescope?
Optical telescopes are strictly used for viewing objects with one's eyes. Many large-scale universal phenomena can be witnessed in visible light. We can observe stars, planets, comets, moons, distant galaxies, and even supernovae. Optical telescopes basically magnify and gather light that we'd otherwise be able to see with the naked eye, were the events and objects we were viewing much closer. However, optical telescopes are very limited in the sense that visible light is only a TINY portion of the entire electromagnetic radiation spectrum. Many astronomical events produce light in high frequencies (especially BIG events such as supernovae, black hole activity, activity in the center of galaxies) that we cannot see with our own eyes, no matter the size of the optical telescope. On the other end is radiation of much lower frequency, which travels more efficiently through matter, allowing us to witness the depths of our own galactic core, the cores of other galaxies, and events happening under the dense atmospheres of other plants.

DVD-ROM is a high capacity?
optical dish
What is electronic bottleneck?
Electronic bottleneck refers to the inability of electronic devices to process optical data at very high speeds. The term is used mostly when trying to justify the need to process ultra high speed data using all-optical devices without the need for optical-electrical-optical conversion.
What optical fibers made of?
High purity glass strands.
