Trick Question: Scientific Imaging
Broadband (RGB) and Narrowband (ex: hydrogen alpha) filters are used to capture and later colorize astronomical images. Which kind of filter would be more useful to produce detailed images once processed?
Narrowband filters, they allow for a small, specific frequency of light to pass through while blocking all others.
What kind of energy does the sun produce?
The sun produces kinetic energy and electromagnetic radiation that is felt as light and heat.
a hypothetical substance that makes up a large portion of the universe, but is difficult to detect because it doesn't interact with electromagnetic radiation
Makes up most of the matter in our universe
