(Answer #1). The critical angle is the largest angle at which light rays inside a diamond can escape. The more a material bends light, the higher the RI Refractive index, the smaller its critical angle.Because diamond has a high RI, it has only a small critical angle, 24.5 degrees.Answer #1). The critical angle is the largest angle at which light rays inside a diamond can escape. The more a material bends light, the higher the RI Refractive index, the smaller its critical angle.
This means that the bonds such as hydrogen bonds and polar attrac â¦ tion between the individual molecules of a substance must be broken so that the molecules can flow past each other in a liquid state. Diamonds have a very high melting point. This is because diamond is a macromolecule.Diamond is made up of single carbon bonds, with four carbons attached to each carbon molecule. In contrast, molecules such as water and carbon dioxide have a set number of atoms per molecule, and that number is very low.his means that the bonds such as hydrogen bonds and polar attrac â¦ tion between the individual molecules of a substance must be broken so that the molecules can flow past each other in a liquid state.
