CHEMISTRY GLOSSARY
X-ray spectrum → spektar X-zraka
X-ray spectrum is a set of characteristic X-ray frequencies or wavelengths produced by a substance used as a target in an X-ray tube. Each element has a characteristic X-ray spectrum, and there is a strong correlation between atomic number and the frequencies of certain lines in the X-ray spectrum.
line spectrum → linijski spektar
Red-hot gases give line spectrum, i.e. is they emit electromagnetic rays of defined wavelengths. That kind of emission line of spectrum is characteristic of each chemical element.
cathode ray → katodna zraka
Cathode ray is a negatively charged beam that emanates from the cathode of a discharge tube. Cathode rays are streams of electrons.
electromagnetic radiation spectrum → spektar elektromagnetskog zračenja
Wavelengths of electromagnetic waves can be shown with the help of electromagnetic radiation spectrum. Electromagnetic radiation spectrum is divided into several areas from γ-radiation of very short wavelengths and great energy to radio waves with wavelengths up to 1 000 m. The human eye can only see a narrow part of the electromagnetic spectrum - visible radiation.
alpha rays → alfa-zrake
Alpha rays are a stream of alpha particles. Alpha rays rapidly dissipate their energy as they pass through materials. They were discovered by the British physicist Ernest Rutherford (1871-1937), a New Zealander by birth, in 1903.
cosmic rays → kozmičke zrake
Cosmic rays are high energy (1015 eV- 1017 eV) nuclear particles, electrons, and photons, originating mostly outside the solar system, which continually bombard the Earth’s atmosphere.
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.
