Which consequence results when contaminants distort precision telescope mirror surfaces?

A)Decreased image resolution due to interference
B)Increased chromatic aberration from dispersion
C)Reduced thermal expansion coefficient effects
D)Elevated signal attenuation from reflection

💡 Explanation

Reduced image resolution occurs because variable thickness from contaminants induces thin-film interference, altering reflected light wavefronts. Because of light path differences, constructive and destructive interference results in blurred images, therefore resolution declines, rather than chromatic aberration, thermal effects, or signal attenuation.
