Which effect is seen when unpolarized light passes through birefringent film under mechanical stress?

💡 Explanation

Stress causes temporary alignment of polymer chains resulting in stress-induced birefringence because light components refract differently along those chains rather than remaining isotropic. Therefore, interference colors appear, rather than other changes to conductivity or constant refraction.
