Would a wave of light that's stopped be visible? I'd imagine that light can't reflect off of light. And isn't light only visible to us when it enters our eyes?

  Perhaps you could pass your eye through the light and see a brief flash when you reach it?

    No because that would require some form of energy transfer. To observe the state of the system you have to take energy from it. I suspect your very presence would likely be a big contributor to this not working to start with too. Disclaimer: I am not a physicist; merely an engineer.
