Can we store light energy by using the concept of total internal reflection, as in case of diamond? eg. cutting diamond in such angle on its edges as to when light enters at a specific angle, it gets totally internally reflected for some time, giving us temporary storage

Dear student,

You can store light only as a temporary basis in a Diamond, till the light either comes out of the Diamond (when it makes an angle of incidence from Diamond to air equal to 24.40). This is the reason, when the stored light makes this angle of incidence and comes out of the diamond, it makes the diamond sparkle.

Hope this answers your question.
