The video explains wave interference, where two waves meet and form a new wave. Constructive interference occurs when the crests of two waves align, creating a larger wave. Destructive interference happens when waves combine to form a smaller wave than the originals.

What is the term used when two waves meet and form a single wave?

• Interference

• Reflection

• Diffraction

• Refraction

What happens during constructive interference?

• The waves pass through each other without interaction.

• The waves cancel each other out.

• The waves reflect off each other.

• The crests of two waves align to form a larger wave.

Which of the following is true about constructive interference?

• It creates a wave larger than the original waves.

• It occurs when the troughs of two waves meet.

• It only happens in sound waves.

• It results in a smaller wave.

What is the result of destructive interference?

• A wave that is the same size as the original waves.

• No change in wave size.

• A wave smaller than the original waves.

• A wave larger than the original waves.

During destructive interference, how do the waves combine?

• The crests of both waves meet.

• The troughs of both waves meet.

• The waves combine to form a smaller wave.

• The waves do not interact.
