Question
The electric field component of a plane wave traveling in a lossless dielectric medium is given by . The wavelength (in m) for the wave is ________.
Correct answer
8.85 to 8.92
Solution
The given electric field expression is .
Comparing this with the standard wave equation , we identify:
Phase constant .
The wavelength is related to the phase constant by:Substituting the value of :The range provided is 8.85 to 8.92.
