Which consequence results when strained glass exhibits birefringence?

💡 Explanation

Stress causes spatial variation in the refractive index, with birefringence emerging; this causes polarized light to split into two rays experiencing different refractive indices. Stress visualisation via photoelasticity occurs, because applied stress causes varying interference patterns, therefore stress can become visible, rather than changes in expansion.
