To understand the formula representing a traveling electromagnetic wave. light, radiant heat (infrared radiation), x rays, and radio waves are all examples of traveling electromagnetic waves. electromagnetic waves comprise combinations of electric and magnetic fields that are mutually compatible in the sense that the changes in one generate the other. the simplest form of a traveling electromagnetic wave is a plane wave. for a wave traveling in the x direction whose electric field is in the y direction, the electric and magnetic fields are given bye? =e0sin(kx? ? t)j^,b? =b0sin(kx? ? t)k^.this wave is linearly polarized in the y direction.1.a. in these formulas, it is useful to understand which variables are parameters that specify the nature of the wave. the variables e0 and b0are the of the electric and magnetic fields. choose the best answer to fill in the blank.1. maxima2. amplitudes3. wavelengths4. velocitiesb. the variable ? is called the of the wave. choose the best answer to fill in the blank.1. velocity2. angular frequency3. wavelengthc. the variable k is called the of the wave.1. wavenumber
