Question 5 (1 point)
Look at the following picture of a gas in a canister exposed to mutliple wavelengths of light

Which of the following statements is most accurate about the gas?

a
The gas does not absorb any light
b
The gas absorbs light with a wavelength that corresponds to the color green
c
The gas reflects the light that enters it
d
The different colors of the light do not merge in the gas and instead, the gas keeps them separated

Answer 1

Here are the answers to your questions:

Question 2: The International Astronomical Union (IAU) has named several of the constellations in the sky, but overall, most of the constellations we know of were discovered and named by:

• b The Greeks

Question 3: Why is there a section of light called the 'visible spectrum'?

• d The visible spectrum is the part of the electromagnetic spectrum that can be seen by human eyes

Question 4: Which of the following would be an example of non-visible light?

• d All of the above (Radio, Infrared, Ultra-Violet)

Question 5: Look at the following picture of a gas in a canister exposed to multiple wavelengths of light. Which of the following statements is most accurate about the gas?

• The answer cannot be determined without seeing the picture, but typically, if the question refers to gas absorbing certain wavelengths, the most accurate statement is likely related to absorption. If the gas absorbs a specific wavelength corresponding to a color (like green), then:
  • b The gas absorbs light with a wavelength that corresponds to the color green would be correct if it is specifically designed to reflect that. Otherwise, it could depend on the context of the image.
