Which risk arises when an interferometric gravitational wave detector underestimates mirror surface curvature?

💡 Explanation

Increased thermal gradients will create thermal lensing because nonuniform heat induces a refractive index change within the mirror based on prior variation in curvature, resulting in blurred or distorted signal rather than high focusing. Interferometers calibrate to predicted curvature.
