Understanding Wave Properties

What is the primary function of waves in energy transfer?

• To move particles

• To change the medium

• To create sound

• To transfer energy from one place to another

How does inhaling helium affect the sound of your voice?

• It makes your voice louder

• It makes your voice higher

What happens when two waves are perfectly in sync?

• They cancel each other out

• They stop moving

• They change direction

• They create a larger wave

What is resonance?

• The bending of waves

How do waves interact with very small objects?

• They miss them

• They absorb them

• They pass through them

• They reflect off them

What is refraction?

• The reflection of waves off a surface

• The cancellation of waves
