← HistoryWhich outcome was more likely when Medieval Islamic lenses suffered bubbles?
A)Chromatic aberration worsened significantly
B)Focal length became unpredictable
C)Image distortion became intractable✓
D)Lens grinding process stopped entirely
💡 Explanation
Image distortion increased due to light scattering at air-glass interfaces within bubbles, a process known as Tyndall effect. Therefore, image fidelity suffered, particularly for astronomical observations, rather than only affecting the lens's chromatic dispersion or focal length.
