question 190

Multiple Choice

How does the angular resolution (sharpness) of the images obtained from radio telescopes using very long baseline interferometry (VLBI) compare to the typical angular resolution of optical telescopes?

• A) VLBI images are about 10 times less sharp than the best optical images.
• B) VLBI images are much sharper.
• C) VLBI images are very much less sharp because of the longer wavelength.
• D) VLBI images have about the same resolution as the best optical images, about 0.2 arcseconds.

Definitions:

Molecular Ion Region

The part of a mass spectrum that shows the peaks corresponding to the molecular ions, providing information about the molecular weight of a compound.

Mass Spectrum

A graph or data set representing the distribution of ions by their mass-to-charge ratio, used to identify or quantify substances.

2-Hexanol

A secondary alcohol with the molecular formula C6H14O, characterized by an hydroxyl group attached to the second carbon of a six-carbon linear chain.

M/z Value

The mass-to-charge ratio, a critical parameter in mass spectrometry for identifying the molecular weight and structure of compounds.
