The scale value will be larger, because the water cup is equivalent to a convex lens. It will be enlarged

When a ruler is inserted obliquely into the water, does the scale become denser or denser?

Ha, so the part of the scale in the water will become shorter, but the scale line will not decrease, so it will become denser
I hope it's clear
