Purple is considered the hardest color for the human eye to see because it has the shortest wavelength in the visible light spectrum, making it more difficult for our eyes to focus on and perceive accurately.
The name of the hardest solid is a diamond; it is the hardest object known to humankind.
Diamond is often considered one of the hardest naturally occurring materials in the world. However, a synthetic material called aggregated diamond nanorods has been found to be even harder, making it one of the hardest solids known to date.
The hardest surface on Earth is diamond. It is considered the hardest because of its strong molecular structure, which consists of carbon atoms arranged in a tightly bonded crystal lattice. This structure makes diamond extremely resistant to scratching and abrasion, making it the hardest naturally occurring material known to man.
A diamond can shatter if hit with a hammer. While diamond is the hardest naturally-occurring mineral known, it is also brittle. The hardness means that it is difficult to cut, but the brittleness means that it is likely to splinter or shatter if enough pressure is exerted. In the case of a diamond hit with a hammer, the likelihood that the diamond will shatter will increase with the force of the hammer (based mostly on the weight) and will further increase if the diamond has any significant inclusions (indicated by a flaw in the diamond). Given the value of a diamond, it is highly recommended that you do not try this at home.
