Image hosted by Photobucket.com OK Class... for your final question.

If the radio signal left alpha centaurs 150,000 years ago and a Laser signal went out fifty years later... how many lightyears till the Laser passes the Radio signal???

Show your work.

Extra Points if you answer the question without a calculator

It will be fifty years behind the radio signal. It will not pass it.

Tricky. Hey, am I the only man on this planet that thinks that light moving as a body through space is nonsense? I think the idea of "light years", as most understand it, is absurd.

The speed of light is the speed of light. Laser light propogates at the same speed as microwave radiation.

Come on--give us all the information we need to solve this story problem! Everyone knows it depends on whether the radio signal was sent via AM or FM, and what the color of the laser beam is.
