Question

How does light bend if it's going from an object with a better density through an object with a lower density?

Answer 1

Hint : Density may be a measure of mass per volume. the typical density of an object equals its total mass divided by its total volume. An object made up of a relatively dense material (such as iron) will have less volume than an object of equal mass made up of some less dense substance (such as water).

Complete Step By Step Answer:
The normal may be a line perpendicular (forming a 90 degree angle) to the boundary between the 2 substances. The bending occurs because light travels more slowly during a denser medium. Since the sunshine is passing from air (less dense) into water (more dense), it's bent towards the traditional .
When light travels from a denser medium to a rarer medium, it bends faraway from the traditional , as illustrated to the left. This behavior follows from Snell's Law. As you saw before, the larger angle must be within the medium having the lower index of refraction. On the previous pages, that was medium 1, but here it's medium 2.
The angle and wavelength at which the sunshine enters a substance and therefore the density of that substance determine what proportion the sunshine is refracted. The bending occurs because light travels more slowly during a denser medium.

Note :
Density of any substance or medium determines the quantity of sunshine which will be refracted. The upper is the density of any medium, the upper are going to be the amount of atoms or molecules during a given medium and hence more obstruction are going to be produced for light. High density also causes a high index of refraction.
