你令我諗起path difference XDDD

refrective index?
sin i /sin r = n =]
total internal reflection 同 refrective index 有關XDD

light rays is not difficult =]

they are just wave only XD
讀到預科你會知點解天空會係藍色
但係黃昏會變紅色._.

we skip the wave part` and started to talk about light rays immediately xD`

sounds interesting -!`;]
is that about reflection?
just make a guess xD

geog mentioned a little bit about why the sea is blue in color ;]

it is diffraction(散射) =v=
but it need to know the atomic physics =v=
it is about the energy ... and the wavelength of light=v=

stupid me -v-"

atomic physics`
something like chemistry -v-`

you can still remember these things so clearly xD
