    我們可以看見光線穿越過混濁白色的澱粉溶液 是因為 水把光芒反射到我的眼裡?(真假)

    please explain~

    當然是假 水是透明 無色的 所以光在穿越它的時候是不會反射的 光線是被溶液中的澱粉所反射到我的眼睛的

    This is kind of weird statement, as I know a beam of light is invisible after it pass through a starch solution, but it can be seen as it passes through colloid.

    after it pass ...==> after it passes
