  1. Congratulations Hiro, absolutely right.
    Moonlight shines on the spray from the waterfall to cause a ‘moonbow’.
    This is the Victoria Falls in Zambia/Zimbabwe, and this sight can often be seen when there is a full moon.
    By the way it is not really ‘moonlight’, it is sunlight reflected by the moon.
