Which of the following would you experience first?

• Light from lighting

• Sound from thunder

• You would experience them at the same time

Why can electromagnetic waves travel in space?

• They vibrate so quickly they create their own medium

• They are able to reflect off planets' atmospheres to travel

• They do not require a medium to travel

• They merge with other waves to travel
