Question:medium

In which of the following, total internal reflection does not occur ?

Show Hint

To distinguish between refraction and total internal reflection phenomena, look at whether light crosses a boundary or gets trapped inside. Atmospheric effects (twinkling, early sunrise) are caused by continuous bending (refraction), whereas light trapping (fibers, diamonds, mirages) depends on TIR.
