Homework Answers
The universe contain vast range of light wavelengths known as electromagnetic spectrum.
Electromagnetic spectrum includes everything from gamma rays at the shortest wavelengths to radio waves at the longest wavelengths.
Human eye will respond to wavelengths from about 400to 700 nanometers.
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye.
Infrared comes under range above 700nm wavelength and are not visible to naked eyes of human
Hence Humans can't see infrared light and statement is false

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...
