If a sound wave travels from air into water, which phenomenon is most likely to occur at the boundary?
Refraction
Diffraction
Absorption
Vacuum
A student claps their hands in a large empty room and hears an echo. Which wave behavior does this demonstrate?
Reflection
Refraction
Diffraction
Absorption
Why can’t mechanical waves travel through a vacuum?
There is no medium for the wave to transfer energy
The vacuum absorbs all waves
Waves are reflected in a vacuum
Waves are refracted in a vacuum
A wave moves from a solid to a gas. Predict what will happen to the speed of the wave and explain why.
The speed decreases because particles in a gas are farther apart than in a solid
The speed increases because gases are lighter
The speed stays the same because the medium doesn’t matter
The speed increases because solids slow down waves
A student shines a flashlight at a glass window. Some light passes through, some bounces back, and some is absorbed. Which terms best describe these three behaviors?
Transmitted, Reflection, Absorption
Reflection, Refraction, Diffraction
Absorption, Diffraction, Refraction
Refraction, Reflection, Transmission
