The change in refractive index for tempered glass upon annealing is ________ when compared to non-tempered glass.
A)Greater
B)The same as
C)Less than
D)None of the above

Question

Quizplus · Accepted Answer

The change in refractive index for tempered glass upon annealing is greater than for non-tempered glass because the tempering process introduces stresses that alter the glass structure, and annealing relieves these stresses, causing a more significant change in the refractive index.
