Light reflection by traffic light after rain

  1. Apr 25, 2009 #1
    Hi. I need to write up a short one paragraph on a picture I took-- I just need hints or suggestions so I can go and research the effect myself. Any insights would be greatly appreciated.


    I have a picture of a traffic light (red). The ground is wet after rain. The red light is smeared out all over the ground. Hope this makes sense.
    Here is a similar picture I found online.

    Can someone explain this phenomena?

    Thank you.

    Here's a hint. What optical properties would the street have to have in order for you to see a non-smeared image of the light?

    Hum. Are you trying to get me to think about the difference between diffuse reflection-irregularities and impurities in the road- and regular
    reflection. I know Theta incidence = theta reflection.
    The water acts like a mirror? or lens? and create an inverted image right?
    I could get be wrong here.
