200

What is the lowest point on a wave called?

The Trough 

200

What is the height of a wave called?

Amplitude

What state of matter does not receive any particle interaction ? Why? 

Solid because their atoms do not move/slide past each other, they just vibrate in place.

What is the difference between a series circuit and a parallel circuit? 

In a series circuit, all components are connected on a single pathway. In a parallel circuit, there are multiple pathways of connection.
