Maxwells equations in a dielectric resemble those in vacuum (Equations 29.629.9) but with 0 replaced by

Maxwell’s equations in a dielectric resemble those in vacuum (Equations 29.6–29.9) but with ε₀ replaced by kε₀, where k is the dielectric constant introduced in Chapter 23. Show that the speed of electromagnetic waves in a dielectric is c/√k.
