Waves: Wavelength and Frequency

The video tutorial explains the fundamental characteristics of waves, including amplitude, wavelength, and frequency. It describes wavelength as the distance between identical points on consecutive waves, usually measured in meters or centimeters. The period of a wave is the time it takes to travel one wavelength, while frequency is the number of complete waves passing a point per second, measured in hertz (Hz). The tutorial also mentions that FM radio frequencies are measured in megahertz (MHz).
