   Bot true. Put your light detector in the light's path and the light will   
   be detected.   
      
   A stream (or ray) of light behaves the same way as a stream of water:   
   if it's pointed at you, you'll be lit (or wet); if it's not, it won't   
   affect yopu.   
      
   Simple, really.
