    Answer:

    Answer E is false because the two instruments see the flickering of the stars, so this is not a characteristic of a reflector

    Explanation:

    Let’s analyze the characteristics of a reflecting telescope.

     

    – use reflection to create images

    – does not have the chromatic aberration problem

    Let’s see the responses a, b, c and d are characteristics of a refractor

    Answestars, so this is not a characteristic of a reflector

    Answer E is false because the two instruments see the flickering of the stars, so this is not a characteristic of a reflector
