빛의 파장
The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and…
전자기파 스펙트럼
The electromagnetic spectrum consists of all the types of electromagnetic radiation arranged according to their frequency and wavelength. Each of the…
간섭과 회절
Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a…
광전효과
When light of a particular wavelength strikes a metal surface, electrons are emitted. This is called the photoelectric effect. The minimum frequency…
보어 모델
Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei…
방출 스펙트럼
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner…
드브로이 파장
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on…
불확정성 원리
Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined…
원자의 양자역학 모델
Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave…
양자수
It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one…
원자 궤도(오비탈)
An atomic orbital represents the three-dimensional regions in an atom where an electron has the highest probability to reside. The radial…
파울리의 배타원리
The arrangement of electrons in the orbitals of an atom is called its electron configuration. We describe an electron configuration with a symbol…
원자 궤도(오비탈)의 에너지
In an atom, the negatively charged electrons are attracted to the positively charged nucleus. In a multielectron atom, electron-electron repulsions…
쌓음 원리와 훈트 규칙
To determine the electron configuration for any particular atom, we can build the structures in the order of atomic numbers. Beginning with hydrogen,…
다전자 원자의 원자 배치
The alkali metal sodium (atomic number 11) has one more electron than the neon atom. This electron must go into the lowest-energy subshell available,…
원적외선 레이저 방출 및 그들의 주파수의 측정을 특성화
The generation and subsequent measurement of far-infrared radiation has found numerous applications in high-resolution spectroscopy, radio astronomy,…
싱크 로트 론 엑스레이 Microdiffraction 및 광물 및 암석 샘플의 형광 이미징
In this report, we describe a detailed procedure for acquiring and processing x-ray microfluorescence (μXRF), and Laue and powder…
유도 열 작은 자기 영역을 둘러싼 물 근처-적외선 온도 측정 기술
A technique to measure the temperature of water and non-turbid aqueous media surrounding an induction-heated small magnetic sphere is presented. This…
