Title: How does the speed (in a vacuum) of a high-frequency electromagnetic wave compare with a ... Post by: hermiz on Sep 9, 2017 How does the speed (in a vacuum) of a high-frequency electromagnetic wave compare with a low-frequency electromagnetic wave?
A) the lower-frequency wave has the higher speed because speed is inversely related to frequency B) the two waves have the same speed because the speed of light is constant C) the lower-frequency wave has the higher speed because it has the longest wavelength D) the higher-frequency wave has the higher speed Title: Re: How does the speed (in a vacuum) of a high-frequency electromagnetic wave compare with a ...
