Which of the following properties of an astronomical image will improve if the image is made in blue light instead of red light,if all other factors are held constant?
A) magnification
B) angular resolution
C) light-collecting power
D) polarization

Question

Quizplus · Accepted Answer

The angular resolution of an astronomical image is directly proportional to the wavelength of light used to capture the image. Blue light has a shorter wavelength than red light, so using blue light instead of red light will improve the angular resolution of the image. Magnification, light-collecting power, and polarization are not directly affected by the wavelength of light used.
