This is awesome! I am happy to have purchased a full year subscription. As a military veteran, I am constantly filling out standard forms for military, the veterans administration, etc., so this is a great way to fill out a form neatly, and methodically, instead in my own hand writing. Thank you for this wonderful service.

I have tried a couple other products and they do not compare with the ease of the PDFfiller product. I am over 80 and faced with a great deal of medical paperwork regarding insurance, test results, doctors paperwork and hospital paperwork. My handwriting is a bit shaky with age and at times people can not read what I have attempted to write. I used PDFfiller on a several pages of a doctor's information form and it was a breeze and people could read my answers. The doctors staff wanted to know how I did it and thanked me many times for doing it with PDFfiller.

For pdfFiller’s FAQs

Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.

Why do radio telescopes have such poor resolution?

Resolution of a Radio Telescope. 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.

Why do radio telescopes have to be so 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 must radio telescopes be large and concave?

How are they different? 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 are telescopes so big?

Large telescopes capture more light than small telescopes. More light means that dimmer objects are visible, and there is more light to be analyzed. And this is the reason why larger telescopes are made.

Do radio telescopes have better resolution than optical telescopes?

Radio telescopes have poorer angular resolution than optical telescopes because radio waves have a much longer wavelength than optical waves.

How are optical and radio telescopes different?

Optical telescopes use polished mirrors or glass lenses to focus visible light as it comes in through the aperture. Radio telescopes are used to study much longer wavelengths than visible light. Often, radio telescopes use a dish to focus the radio waves onto the receiver.

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.
