Wave Interactions

What happens when two waves occupy the same space?

• They create a vacuum.

• They cancel each other out.

• They form a superposition.

• They reflect off each other.

What is the principle that allows two waves to occupy the same space?

• The principle of relativity

• The principle of superposition

• The principle of conservation

• The principle of uncertainty

Which of the following best describes an interference pattern?

• A pattern formed by the polarization of waves.

• A pattern formed by the superposition of waves.

• A pattern formed by the diffraction of waves.

• A pattern formed by the reflection of waves.

What is the result of constructive interference?

• A wave that disappears.

• A wave that stands still.

• A wave with doubled amplitude.

• A wave with reduced amplitude.

What does complete destructive interference result in?

• A wave with maximum amplitude.

• A wave with half the original amplitude.

How do noise cancellation headphones work?

• By converting sound waves into electrical signals.

• By blocking all external sound waves.

• By amplifying background noise.
