ISOTOP: Same Proton

Kaedah ini untuk mengingati maksud isotop iaitu unsur yang mempunyai bilangan

proton yang sama.

ANTINOD AT Amplitud Tinggi

Kaedah ini adalah untuk mengingati maksud antinod iaitu dengan mengingati AT yang

bermakna amplitud tinggi.

BIASAN GELOMBANG AIR DCD( Dalam cetek Dekat)// DST (Deep shallow towards)

Kaedah ini untuk mengingati arah perambatan gelombang apabila gelambang air

merambat dari kawasan dalam ke cetek ia akan mendekati garis normal.

BIASAN GELOMBANG AIR: CDJ (Cetek Dalam jauh) // SDA (Shallow deep away)

Kaedah ini untuk mengingati arah perambatan gelombang apabila gelambang air

merambat dari kawasan cetek ke dalam ia akan menjauhi garis normal.
