objectives


1. describe the characteristic of the universe in terms of distance, and organization.

2. identify the visible and nonvisible parts of ther electromagneticspectrum.

3. compare refracting telescopes and reflecting telescopes.

4. explain how telescopes for nonvisible electromagnetic radiation.

compare the visible and invisible spectrum

compare the refracting telescope and the refracting telescope.

a refracting telescope is a telscope that uses lenses to gather and focus light from distant objects. and the reflecting telscope uses mirrors to gather and focus light from distant objects.the refracting telescope has clear lens. one problem that they had with the refracting telescope was that it was difficult to make a very large lense of the require strength and quality. but their was guy who knew how to fix the problem of the refracting telescope and his name was isacc newton. he was the one who build the refracting telescope and able ton fix the require strength and quality of the telescope to view the image.

invisible light telescopes and spaced based telescopes.

telescopes for invisible light are diffirent from telescopes for visible light:


1. the visible light telescopes can attract radiation.


2. the radiation travels to earth to power our elections.


3. the radiation can't be seen by human.


4. the radiation powers many different types of electronics.


5. the invisible telescope can also attract light that can't be seen.


spaced based telescopes are a solution for telescopes on earth which have to deal with the atmosphere getting in the way:


1. the spaced based telescope can see light from different stars.


2. this telescope can also attract radiation.


3. spaced based telescopescan also attract radiation to travel to earth.


4. the radiation powers many electronics from earth just like the invisible light.


5. this telescope can't see our solar radiation.
