Random Trivia Tidbit - Radio Waves vs Sound Waves

My Mom's a big ole trivia geek too...


She just sent this my way:

Because radio waves travel at 186,000 miles per second and
sound waves saunter at 700 miles per hour, a broadcast voice
can be heard sooner 13,000 miles away than it can be heard
at the back of the room in which it originated.

Neat!
