Equation 16.3, y = A sin (2πft - 2πx/λ), gives the mathematical representation of a wave oscillating in the y direction and traveling in the positive x direction. Let y in this equation equal the electric field of an electromagnetic wave traveling in a vacuum. The maximum electric field is A = 156 N/C, and the frequency is f = 1.50 × 108 Hz. Plot a graph of the electric field strength versus position, using for x the following values: 0, 0.50, 1.00, 1.50, and 2.00 m. Plot this graph for

(a) A time t = 0 s and

(b) A time t that is one-fourth of the wave's period.
