-- Because they can't be efficiently transmitted or collected, on account of the
ridiculously humongous antenna size required.
-- Because they're too strongly absorbed by atmospheric gases or water vapor.
-- Because they can't be generated with currently available technology.

Why can telescopes only see some parts of the electromagnetic spectrum?
Simply because there is a small magnet inside that is only powerfull enough to see some parts.
Why is it useful to examine the universe using parts of the electromagnetic spectrum other than visible light?
Different parts of the electromagnetic spectrum give different types of information.Different parts of the electromagnetic spectrum give different types of information.Different parts of the electromagnetic spectrum give different types of information.Different parts of the electromagnetic spectrum give different types of information.
Give some examples of electromagnetic radiation and how the relate to visible light?
Electromagnetic radiation is used in our every day life Learn more with this website electromagnetic radiation | Spectrum, Examples, & Types
How much of the electromagnetic spectrum does visible wavelengths makes up?
In the full spectrum, humans can only see 3% of the rays. Other animals can say more, some scientists predict cats see 20% of the spectrum.
Why does the continuous electromagnetic spectrum have a sharp limit on the short wavelength end?
There is a simple explanation for the sharp limit on the short wavelength end of the electromagnetic spectrum. The shortest electromagnetic waves are generated by the reactions of subatomic particles. At some point, it just isn't possible to generate a higher frequency electromagnetic wave. We can imagine them, but they cannot be "made" by us (in particle accelerators) nor are they "caused to occur" in nature (by catastrophic cosmic events).
Why are some parts of the electromagnetic spectrum called light and others called waves?
No reason. Light is an electromagnetic wave so you can call any part of the spectrum either.
Is the visible spectrum dangerous?
No, it is not dangerous. It is just the colors that are absorbed by the light. Some parts of the electromagnetic spectrum are dangerous, however. To learn more in depth and to get more of an explanation on the visible spectrum and the electromagnetic spectrum, visit wikipedia.
Why can telescopes only see some parts of the electromagnetic spectrum?

In some parts of the electromagnetic spectrum the atmosphere is described as opaque What does this mean for remote sensing?
Most waves from the em spectrum reflect off the atmosphere and the ozone layers Hope this helped

What are some animals that can locate the electromagnetic spectrum?
It is not at all clear what you mean by locating the electromagnetic spectrum. Electromagnetism exists at innumerable locations throughout the universe. Vision is a sense that uses a part of the electromagnetic spectrum, and lots of animals can see. Some animals, such as bees, can see in ultraviolet frequencies that the human eye does not see.
How you receive heat and light from the sun?
Energy from the Sun reaches Earth as radiation from various parts of the electromagnetic spectrum. Some of this energy . Some of this energy is converted to heat. Some remains as visible light.
What are some problems in using various regions of the electromagnetic spectrum?
It is very easy to use!

Why is it useful to to examine the universe using parts of the electromagnetic spectrum other than visible light?
Because many stars emit energy unevenly over the electromagnetic spectrum. Thus extremely energetic objects would be brighter in X-rays (more energetic than visual light) and some brown dwarfs would be easier to perceive in the infrared. Combining images from across the spectrum avoids the three blind men and the elephant issue.
Which part of the electromagnetic spectrum is used in IPL treatments?
All of the visible and some of the infra-red, up to about 1200nm.
Are sound waves part of the electromagnetic spectrum?
Sound waves and electromagnetic waves are different. Sound is composed of density waves in the air or some other form of matter. Sound is a mechanical compression-rarefaction wave. The different types of electromagnetic waves are gamma rays, X-rays, ultraviolet rays, visible light, infrared radiation, microwaves, and radio waves.
