Witryna12 gru 2016 · The typical example is a plastic bag, which is transparent to visible light, but opaque to infrared light. This means that it mostly lets visible light through (no absorption, no heating), while capturing infrared light (absorption, heating). The human body is mostly transparent to both very high and very low frequency light. The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, a…
