subject | fact |
infrared | has frequency 3 THz to 430 THz | ![]() |
has wavelength 700 nm to 100 μm | ![]() | |
has acronym IR | ![]() | |
has definition That part of the electromagnetic spectrum that lies beyond the red, having wavelengths from about 7500 Å to a few millimeters (about 1011-1014 Hz). Infrared radiation is caused by atomic transitions, or by vibrational (near-IR) and rotational (far-IR) transitions in molecules. (IRe1, IRc1, IRs1: the e sources are extended; the c sources are unresolved; the s indicates an infrared nebula surrounding a visible star.) | ![]() | |
has definition The region of the electromagnetic spectrum from a wavelength of about 1 μm (10-6 m) to about 200 μm. The region from 1 to 5 µm is the near infrared: 5-30 is the mid infrared and 30-200 µm is the far infrared. | ![]() | |
