What substances? Depends on their density, the lower density floats on top. For example, oil floats on top of water
I believe that it is called refracting...
I can't give you the actual number of turns, because it's the RATIO
that counts.
However many turns the primary has, the secondary should have
about TEN TIMES that number. Then the transformer will multiply
the primary voltage by 10 ... 120 volts of AC at the primary will
become 1,200 volts of AC at the secondary.
Note that it HAS TO be AC. If the transformer is supplied with DC,
then 120 volts at the primary becomes zero volts at the secondary
and a big cloud of stinky smoke in the room.
Answer:
I'm sure its transverse, longitudinal and surface

sorry if I'm wrong
