Exam-style question
Try this first
CCD quantum efficiency: Pick the detector advantage that improves faint-object imaging. This tests Calculate angular magnification for simple telescopes. in Astronomical telescope using two converging lenses.
- A.CCD quantum efficiency answer: High quantum efficiency records more arriving photons as useful signal.
- B.CCD quantum efficiency distractor: It doubles the wavelength of starlight.
- C.CCD quantum efficiency misconception: It removes the need for calibration frames.
- D.CCD quantum efficiency off-scope: It changes a galaxy redshift.
Model answer
What a good answer should say
- The correct option is CCD quantum efficiency answer: High quantum efficiency records more arriving photons as useful signal.
Explanation
Why this works
It is correct because it applies Astronomical telescope using two converging lenses evidence to Calculate angular magnification for simple telescopes.. The other options are incorrect because they swap in a different astrophysics measurement, telescope property or cosmology idea.
