An electromagnetic wave travels past you. At a certain instant of time (call this to be t the magnitude of the electric field at your location is at its maximum value Eo and is pointing in the +y direction. As the electromagnetic wave moves past you, the magnitude of the electric field decreases 0), until it becomes zero. The time taken for this to occur is measured to be 1.0 ns. (a) Determine the wavelength of this em wave and report your final answer using only two significant figures. (b) Could this em wave be visible light? Please explain your reasoning.
