Which consequence results on telescope lens when dust accumulates?

💡 Explanation

Dust causes diffraction, resulting in destructive interference, therefore reducing image contrast. This happens because scattering redirects light away from its original path, rather than refracting the light evenly like a clean lens, which would maintain contrast.
