6B-1 Wave Parameters
In Figure 6-lb, the amplitude A of the sinusoidal wave is shown as the length of the electric vector at a maximum in the wave. The time in seconds required for the passage of successive maxima or minima through a fixed point in space is called the period, p, of the radiation. The frequency, V, is the number of oscillations of the field that occur per second1 and is equal to Up. Another parameter of interest is the wavelength, X, which is the linear distance between any two equivalent points on successive waves (e.g., successive maxima or minima).2 Multiplication of the frequency in cycles per second by the wavelength in meters per cycle gives the velocity of propagation Vi in meters per second:
