How energy transmitted?

2 characteristics of electromagnetic waves

distance between two successive peaks and it is expressed in nanometers

the number of vibrations of wave motion per second

The relationship between wavelength and energy is described by

form of photometry which deals with the measurement of light transmitting power of a colored solution to determine the concentration of light-absorbing substances present within it

the measurement of light intensity in a narrower wavelength

the measurement of light intensity using a specific wavelength

Excitation of electrons from lower to higher energy state (It measures the light emitted by a single atom burned in a flame)

Element is not excited by merely dissociated from its chemical bond and placed in an unionized, unexcited, ground sta

used to break chemical bonds and form free, unexcited atom

The unknown sample is made to react with a known solution in the presence of an indicator

It determines the amount of light blocked (reduction of light) by a particulate matter in a turbid solution

It determines the amount of scattered light by a particulate matter suspended in a turbid solution

nephelometry: Light scattered by particles is measured at an angle, typically ___

It determines the amount of light emitted by a molecule after excitation by electromagnetic radiation

It uses two monochromators in FLUOROMETRY

selects the wavelength that is best absorbed by the solution to be measured

prevents the incident light from striking the photodetector

The chemical reaction yields an electronically excited compound that emits light as it returns to its ground state, or transfers its energy to another compound, which then produces an emission

It is based on measuring changes in colligative properties of solutions that occur owing to variations in particle concentration.
