An electromagnetic wave travels in a vacuum. The wavelength of the wave is tripled. How is this accomplished? by tripling the frequency of the wave by tripling the magnitudes of the electric and magnetic fields that comprise the wave by reducing the frequency of the wave by a factor of three by reducing the speed of the wave by a factor of three by tripling the speed of the wave
