Electromagnetic spectrum table

These instruments constitute a class of spectroradiometric analysers generally encountered in the chemical process industries and employed to monitor wavelengths between the middle infra-red (MIR) and ultra-violet (UV) regions of the electromagnetic spectrum (Table 6.8). 

Opacity. Both glass and plastic absorb light in the UV range of the electromagnetic spectrum (Table 3.2). Quartz should be used where this is important, e.g. in cells for UV spectrophotometry (see p. 165) or photochemistry. 

Table 3.1 summarizes the details of typical sources, absorption cells, dispersing elements and detectors used in different regions of the electromagnetic spectrum. 

A university student recently had a busy day. Each of the student s activities on that day (reading, having a dental x-ray, making popcorn in a microwave oven, and getting a suntan) involved radiation from a different part of the electromagnetic spectrum. Complete the following table and match each type of radiation to the appropriate event ... 

The electromagnetic spectrum is shown in Figure 5.1 and most common spectroscopic methods are shown in Table 5.2. The spectroscopic regions are not exactly defined slightly different boundaries are found in the literature. 

The recent close-encounter, especially with comet Hale-Bopp, focused the attention of the ground-based telescopes in all regions of the electromagnetic spectrum to produce the molecular inventory shown in Table 6.4. Chemical network models for... 

The following table lists the more common materials used for optical components (windows, prisms, etc.) in the infrared region of the electromagnetic spectrum. The properties listed are needed to choose the materials with optimal transmission characteristics.1 2 The thermal properties are useful when designing experiments for operation at elevated temperatures.3-5 This listing is far from exhaustive, but these are the most common materials used in instrumentation laboratories.
