they are never white or colorless. they are coloured. copper oxide is black. so maybe the answer is black. i have never seen any yellow metal oxide. iron oxide is brown in presence of water due to it's fe(3+) ions it's not it's own color i guess.
anybody please answer it.

in igcse. whenever u see something in chapter of waves that looks unfamiliar leave it. my teacher advised me to do igcse papers.
DC generator is different. AC gen. is simple, a coil is moved or a magnet within a fixed coil is moved for change in magnetic field lines cut on the wire and since the lines move further a waveform current is produced with forward (max.) and reverse(min.) direction. note: for a moving coil a "slip ring" is necessary to use for current output to get carried.
they are the same I think and speed decreases, but wave velocity changes...
