Study Notes
Spectroscopy and Electromagnetic Spectrum
- Spectroscopy is the study of the interaction between matter and electromagnetic radiation.
- A spectrophotometer is an instrument used to measure the absorbance or transmittance of electromagnetic radiation by a substance.
Electromagnetic Spectrum
- The electromagnetic spectrum refers to the range of frequencies or wavelengths of electromagnetic radiation, which includes all forms of radiation.
- The electromagnetic spectrum consists of, in order of increasing frequency and energy, radio waves, infrared (IR) rays, visible light, ultraviolet (UV) rays, X-rays, and gamma rays.
Structure of Electromagnetic Radiation
- The fundamental particle of visible light is the photon.
- Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays all consist of electromagnetic waves, which are forms of energy that propagate through space in the form of electric and magnetic fields.
