1

What arrangement are electrodes placed in Interferential current?

Criss cross

2

What is it called when two sinusoidal waves are exactly in phase combine and the waves supplement each other?

Constructive interference

3

What is it called when 2 sinusoidal waves are exactly out of phase which results in cancellation of both wavesS?

Destructive interference

4

What is it called when there is a combination of constructive and destructive intereference resulting in a wave with a beat.

Heterodyne
