Final answer:
Wavelength is the wave's repeating part distance, frequency is cycles per second, and amplitude is half the peak-to-trough height, correlating with wave intensity.
Step-by-step explanation:
In relation to electromagnetic waves, the term wavelength is defined as the distance between two consecutive peaks or troughs in a wave, which is typically measured in meters in the International System of Units (SI). Electromagnetic waves exhibit a broad range of wavelengths extending from kilometers to picometers.
The frequency of the wave is the number of wave cycles that pass a specified point in space within a specified time interval, usually measured in seconds, and is expressed in hertz (Hz). One hertz is equivalent to one cycle per second, with common multiples like megahertz (MHz) and gigahertz (GHz).
Lastly, amplitude represents the magnitude of the wave's displacement, which corresponds to half the height between the peaks and troughs of the wave and is related to the wave's intensity, determining factors like the brightness of light or loudness of sound.
