1 In a vacuum, all electromagnetic waves travel at approximately 3 x 10 8 m/s-the fastest speed possible. 2  When electromagnetic waves travel through matter (for example, light through air or glass), they travel a bit slower than this but rarely less than half as fast as in a vacuum.
The speed of electromagnetic waves in a vacuum. B. c. D. depends upon the wavelength. depends on the photon energy. is the same as the speed of sound. is the same for all waves regardless of wavelength. Slide 25-7. Â© 2010 Pearson Education. Inc. The speed of electromagnetic waves in a vacuum.
