If becks lines appear outside of the perimeter of glass than the glass has higher than the refractive index of the glass. refractive index.
What is perimeter?
A closed path that covers, encircles, or outlines a one-dimensional length or a two-dimensional shape is called a perimeter. A circle's or an ellipse's circumference is referred to as its perimeter. There are numerous uses in real life for perimeter calculations.
If the Becke line runs along the outside edge of the glass fragment, the surrounding medium's refractive index is greater than that of the glass.
