Study Notes
Ultraviolet (UV) Light
- Germicidal UV refers specifically to UV-C light, effective in killing bacteria and viruses.
Relationship Between Frequency and Wavelength
- Inversely proportional relationship exists: as frequency increases, wavelength decreases, and vice versa.
Spin Interaction with Electromagnetic Spectrum
- The interaction that results in a change of spin is known as Electron Spin Resonance (ESR).
Light Wavelength Comparison
- Ultraviolet light has a shorter wavelength than microwave radiation.
Energy Level Transition
- The phenomenon where a molecule jumps from one energy level to another and emits light upon returning is called photoluminescence.
Light Intensity in Solutions
- The intensity of light typically decreases when solutes are present in a solution, due to absorption and scattering.
Non-Photoactive Light Emission
- The type of light emission that occurs without prior exposure to light is known as phosphorescence.
Logarithmic Light Intensity Term
- The term for the logarithm of the ratio of light intensity that passes through a solution to that of the light source is transmittance.
Solutes and Photon Energy
- When solutes interact with light, they can absorb a portion of the energy carried by photons, leading to decreased light intensity.
Light Interaction with Solutions
- Upon striking a solution, light can experience changes in intensity due to absorption, scattering, and transmission influenced by the solute concentration.
