This is a colour-composite of the barred spiral galaxy NGC 5584. Credit: ESO: observations by Susana Randall, Claudio Melo, Swetlana Hubrig; day astronomer Dominique Naef; Henri Boffin (ESO) processed the data and made the colour-composite, and Haennes Heyer (ESO) made the final adjustments.

Violet astronomy is a lecture and an article as part of the astronomy course on the principles of radiation astronomy.

You are free to take this quiz based on violet astronomy at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, and in the course template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

A suggestion is to have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

9. Why is much of the surface of Mars covered with red iron oxide dust when the rocks that compose much of its surface are blue or violet?

Mars has been systematically bombarded with small iron-nickel meteorites or micrometeorites that oxidize in its atmosphere
Mars has been frequently bombarded with hematite containing micrometeorites
asteroid impacts on Mars may have forced iron from near its core into the atmosphere and onto the surface as hematite dust that oxidized
Mars is like Earth in surface hematite composition, but Earth has much more water
precipitation from iron-rich water

Research

Hypothesis:

  1. Violet radiation yields clues through clouds of what's beneath.

Control groups

This is an image of a Lewis rat. Credit: Charles River Laboratories.

The findings demonstrate a statistically systematic change from the status quo or the control group.

“In the design of experiments, treatments [or special properties or characteristics] are applied to [or observed in] experimental units in the treatment group(s).[1] In comparative experiments, members of the complementary group, the control group, receive either no treatment or a standard treatment.[2]"[3]

Proof of concept

Def. a “short and/or incomplete realization of a certain method or idea to demonstrate its feasibility"[4] is called a proof of concept.

Def. evidence that demonstrates that a concept is possible is called proof of concept.

The proof-of-concept structure consists of

  1. background,
  2. procedures,
  3. findings, and
  4. interpretation.[5]
