EM waves travel at what speed in a vacuum?
300,000 m/s
300,000,000 km/s
Answer explanation
This question links to success criteria: I can explain what an electromagnetic wave is and how it travels through different materials.
If you got it correct place a check mark in the question results section. If you got it incorrect place an X in that section. If this was a redemption question, cross out the one X and replace it with a check mark.
