Section 2.5‚ Chapter 18‚ and Section 19.1 Introduction Spectrophotometric determinations based on the Beer-Lambert Law are among the most widely used analytical procedures. These methods involve the measurement of the fraction of incident electromagnetic radiation that is absorbed by a sample. To determine the concentration of a colored species in solution‚ a cuvet containing the solution is placed in the spectrometer‚ which consists of a spectrograph and a photometer. The spectrograph produces

The differences in energy between these lines is produced by electrons going from high to lowe energy orbits and as a result releasing energy and electromagnetic waves with longer wavelengths. This means that these lines are lower in energy when compared to the ultraviolet line spectrum. In addition‚ the ultraviolet lines indicates that electrons is going from high to low energy thus‚ releasing more energy

Light that is visible to the human eye is a small portion of the electromagnetic spectrum which can vary in colour based on the wavelength of what is being seen at any particular time. This visible light has a primary function of causing electrons to become more active with higher energy rates. The colour that is seen revolves around the size of this portion which is noted as the wavelength. White light is a culmination of all colours which is the cause of it being the brightest. Furthermore‚ when

PHOTOGRAPHY The word photography derives from the Greek phōtos means "light" and graphos means "drawing"‚ together meaning "drawing with light". Photography is the art‚ science‚ and practice of creating durable images by recording light or other electromagnetic radiation‚ either chemically by means of a light-sensitive material or electronically by means of an image sensor. Photography has many uses for business‚ science‚ manufacturing‚ art‚ recreational purposes‚ and mass communication. Modern photography

scientific marvels far better and more accurately than watching an episode of Star Trek or reading a Superman comic. First and most important is to analyze why an X-ray works and what it is. These “rays” are high energy‚ low wavelength beams of electromagnetic energy – very similar to the light we can see; only they are completely invisible to us because our eyes lack the ability to detect its wavelength. They are produced by the movement of electrons in atoms. Electrons exist in constant orbit around
