Chapter , Problem 58(choose chapter or problem)
In free space (vacuum), where the net charge and currentflow is zero, the speed of an EM wave is given byv = l/Veo^o- If, instead, an EM wave travels in a nonconducting(dielectric) material with dielectric constant K, thenv = l / y l e ^ . For frequencies corresponding to the visiblespectrum (near 5 X 1014 Hz), the dielectric constant of wateris 1.77. Predict the speed of light in water and compare thisvalue (as a percentage) with the speed of light in a vacuum.
