WebThe electromagnetic spectrum ( EMS) is the general name given to the known range of electromagnetic radiation. Wavelengths increase from approximately 10 -18 m to 100 km, and this corresponds to frequencies decreasing from 3 × 10 26 Hz to 3 ×10 3 Hz. The image below shows the names given to different regions of the EMS. WebFrequency—number of waves passing by a specific point per second. In addition to amplitude, frequency, and period, their wavelength and wave velocity also characterize …
