Answer
Polarization is a method of restricting different plane of transverse waves into the required plane.
Polarization process is done with the help of Polaroids. Polaroids are kept at different angles, these angles are selected according to the wave requirement. Polaroids allows only waves which are aligned to it.
so, this phenomenon is the same in case of polarizing sunglasses as it restricts the unwanted sun waves to pass through it.
That's true.
-- a bell starts ringing (wave) when you tap it (simple pulse)
-- a pond starts rippling (wave) when a stone drops in (simple shock)
-- a guitar strings starts waving when you pluck it
Answer: conductors are substances that allow heat or electricity to pass through . It deals with only the flow of electrons.
Eg. water, copper wire, iron rod, some ceramic materials, metallic nail.
Insulators are materials that do not allow heat or electricity to pass through.
Eg. Book, plastic, rubber, glass, paper

Answer:
If the two plates are of equal density, they usually push up against each other, forming a mountain chain. If they are of unequal density, one plate usually sinks beneath the other in a subduction zone. Hope this helps!
