Indicate which of the following statements about the electromagnetic spectrum and IR spectroscopy are true and which are false. In any cases where the statement is false, explain how or why the statement is false. Infrared (IR) light is in the gamma ray part of the electromagnetic spectrum. Electromagnetic radiation is characterized by its mass and force. UV-Vis spectra are normally scanned in the 4000-600 cm-1 region. The fingerprint region on an IR spectrum is the easiest to interpret. Stronger...

Questions [1] One difference between mechanical waves and EM waves is: only one needs a source, only one needs a medium to disturb. (2) If a color of visible light had a frequency of 621 THz, then the color is: red, orange, yellow, green, blue, violet. [3] Different types of EM waves are categorized by their: amplitude, energy, frequency, wave speed in a vacuum. [4] The prefix infra- means: lower than , higher than, about the same. [5] Any piece...
