I think I figured it out. Handed it in yesterday. Used the equation for velocity, d/t. I was over complicating it a bit I think. Thanks a bunch for your help!

I realize that this is a light problem. but I don't see how I would use the speed of light? with what formula?

Homework, do you mean search on the forums for velocity?

ms is millisecond? not meters per second. so the period of the pulse, or the time that the light source was turned on then off again is 1ms, that is my understanding @berkeman if it were a pulse traveling at 1 m/s it would take 20s to cross 20m. but from my understanding the pulse's velocity is...

Homework Statement If you create a 1 ms light pulse by turning a flashlight on and off, how long will the pulse take to reach the other side of the room 20m away? (in air at standard T and P) what is the length, in m, of the pulse? I realize that light has a wavelength and when you pulse it...
