this program has made my life so much easier - I use it to fill in PDF forms for my doctor visits as well as for business - keeps everything simple and in one place. Very user friendly.

It was a wonderful experience. All the reps were competent, patient and more than willing to offer their assistance for any problem or any issue that I was confronting. And I am happy with the results

What do you like best?
Changing things (like dates) on insurance forms helps us a great deal when the insurance information stays the same and only the date needs changed. (Accord forms). We don't have to completely retype an insurance renewal form. So Handy
What do you dislike?
I have helped a colleague in inputting his information on flyers that had someone else's and the eraser showed lines in the final product. I had to figure out what was going on and I figured out I could increase the eraser to remove items rather than going over it several times (like wite-out tape).
Recommendations to others considering the product:
If you need to make changes to documents that you do not want to retype over and over again, then this product is a handy tool. Also, for doing 'already-made-up-flyers' to use for yourself by adding your own information is great. I used to have to remake everything with Corel Draw. This is waaaaaaay easier!!
What problems are you solving with the product? What benefits have you realized?
Non really for what I use it for.

PDF Filler as tool for Securing PDF files
Very useful, convenient and very easy to use. A great tool for businesses.
I like PDF filler the most when I would like to encrypt and decrypt documents, merge PDF files, crop or rotate PDF pages.
I actually like PDF filler and there is nothing that I do not like in this software. It helped me big time with my PDF documents organization.

A Great Product to create PDF documents
Having client's sign documents and creating forms.
The ability to create, fill and sign PDF documents was the best part about this software for me, personally.
I thought it was worth every penny and I also thought it was beneficial to have a free trial initially as well.

Great for clarity
The ease of using it and the clarity of documents being in the typed form as opposed to me having to handwrite them.
This product is very easy to use. It is very useful for clarity of documents when it comes to being legible.

THE BEST SUPPORT TEAM I'VE EVER FOUND
It is honestly the best and most complete pdf program with all the features. It's fast, intuitive, and their support team is absolutely prompt and efficient. I thought I had to wait like with other programs and help on the Internet, but nothing could be further from the truth: in less than two hours my problem is solved. I am very happy with them.

I love this program easy to use platform. As a student this has been my all in one solution. This is a one stop shop program. Seems like every need as far as documents legal forms can be found here. For myself I would recommend this to anyone who is trying to find a platform that handles all your needs. That really is to say the least I have yet to unlock all the features PDF has to offer. Thank You all the staff at PDF

Why do radio telescopes have to be very large?
Radio telescopes are much larger than optical telescopes because radio wavelengths are much longer than optical wavelengths. The longer wavelengths means that the radio waves have lower energy than optical light waves. In order to collect enough radio photons to detect a signal, the radio dishes must be very large.
Why do radio telescopes have to be very large Quizlet?
T/F Radio telescopes are large, in part to improve their angular resolution, which is poor because of the long wavelengths at which they observe. T/F Radio telescopes are large, in part because the sources of radio radiation they observe are very faint.
Why are radio telescopes much larger than optical telescopes Quizlet?
are larger than optical telescopes because radio wavelengths are much longer than optical wavelengths. The surface can also be more flawed than the lenses and mirrors of an optical telescope.
Is interferometry limited to radio astronomy?
Another drawback is that the maximum angular size of a detectable emission source is limited by the minimum gap between detectors in the collector array. Interferometry is most widely used in radio astronomy, in which signals from separate radio telescopes are combined.
What are the advantages of placing telescopes in space Quizlet?
technology that can eliminate much of the blurring from turbulence and allow telescopes to achieve angular resolution close to their diffraction limit. What are the advantages of putting telescopes in space? Allows us to observe the rest of electromagnetic spectrum that does not reach ground/sea level.
Why must radio telescopes be large and concave?
An optical reflecting telescope and a radio telescope both use a curved reflecting surface to focus the incoming radiation. ... Because radio wavelengths are longer than visible light wavelengths, radio telescopes must have larger diameters than those of visible light telescopes.
Why do single dish radio telescopes have poor resolution?
Why do single-dish radio telescopes have poor resolving power compared to optical telescopes of the same diameter? Because the size of diffraction fringes is proportional to the wavelength of light being focused, and radio waves have longer wavelengths than visible light.
Do radio telescopes have better resolution than optical telescopes?
Angular Resolution Radio telescopes have to be much larger than optical telescopes because the wavelengths of radio waves are so much larger than the wavelengths of visible light. ... Angular resolution is a measure of how small details of an area in the sky can be seen.
Do radio telescopes magnify anything?
A radio telescope similarly “magnifies” its “light” hundreds or thousands of times, because its mirror (the parabolic dish -- which focuses light to its eyepiece, the feed horn) is large relative to the wavelength it is focusing. ... Think of this as your “magnification” of light.
Why do radio telescopes have such poor resolution?
The angular resolution of the telescope is given as. Radio waves have a large wavelength and hence have poor resolution. So, to improve the resolution of the radio telescopes, they are made as large as possible. To increase the collecting area, the radio telescopes are made in the form of arrays.
