CHEMISTRY GLOSSARY
ultraviolet light → ultraljubičasto svjetlo
Ultraviolet light (UV light or UV radiation) is an electromagnetic radiation with a wavelength longer than that of x-rays, but shorter than that of visible light. Ultraviolet light can break some chemical bonds and cause cell damage.
visible radiation → vidljivo zračenje
Human eye can only see electromagnetic radiation of wavelengths form 400 nm to 760 nm. This narrow part of electromagnetic spectrum is called visible radiation. Visible (white) light is a mixture of light of all kind of colours, it can be separated, with the help of a glass prism, into its component colours - visible light spectrum, and each colour corresponds to a certain area of wavelengths:
| Colour | Wavelength / nm |
|---|---|
| purple | 400 - 450 |
| blue | 450 - 500 |
| green | 500 - 570 |
| yellow | 570 - 590 |
| orange | 590 - 620 |
| red | 620 - 760 |
X-ray diffraction → rendgenska difrakcija
The regular array of atoms in a crystal is a three-dimensional diffraction grating for short-wavelength waves such as X-rays. The atoms are arranged in planes with interplanar spacing d. Diffraction maxima occur in the incident direction of the wave, measured from the surface of a plane of atoms, and the wavelength λ of the radiation satisfy Braggs’s law:
X-rays → X-zrake
X-rays are electromagnetic radiation of shorter wavelength than ultraviolet radiation (10-11 m to 10-9 m or 0.01 nm to 1 nm) produced by bombardment of atoms by high-quantum-energy particles. X-rays can pass through many forms of matter and they are therefore used medically and industrially to examine the internal structure.
