a. True
b. False

Answer 1

Option (a), The statement about interference having two types, constructive and destructive, is true.

Step-by-step explanation:

Statement Verification in Physics

The question regarding the types of interference in physics is true. There are indeed two types, named constructive and destructive interference. Constructive interference occurs when two or more waves combine to produce a wave with a larger displacement, whereas destructive interference happens when two or more waves combine to produce a wave with a smaller displacement or even cancel each other out.

Concerning the high-voltage wires, the statement is false. While it is true that these wires are held aloft by insulators, the wires themselves are not wrapped in insulating material due to practicality and cost-effectiveness; instead, they are typically bare and rely on the air gap provided by the insulating connectors to prevent electrical discharge to the towers or ground.
