Which outcome results when uneven cooling causes microscopic cracks within a rapidly quenched glass lens?

💡 Explanation

Stress-induced birefringence appears because internal stresses alter the refractive index, causing polarized light to split according to the photoelastic effect. Therefore, birefringence occurs, rather than chromatic aberration, which results from wavelength dispersion, or total internal reflection, relying on incidence angle.
