Which explanation explains how electromagnetic and mechanical waves travel?

• Neither travel in a vacuum and neither transfers energy

• Both travel in a vacuum and both transfer energy

• Electromagnetic waves can travel through a vacuum and a medium and they transfer energy

• Mechanical waves can travel through a vacuum and a medium and they transfer energy

Why does a leaf that is bumped by a wave not actually move to another position in the water?

• The wave only transfers energy, not matter

• The leaf is too small for the wave to move

• There is friction between the leaf and the water

• The wave does not have enough particles to move the leaf

Which of the following explains properties of waves based on the picture.

• Wave A has more energy than the original wave because its amplitude is the lowest

• Wave A has more energy than the original because its amplitude is the highest

• Wave B has more energy than the original because its amplitude is the lowest

• Wave B has more energy than the original because its amplitude is the highest

If you want to soundproof a room to have the least amount of echo, what materials would you choose to line the walls?

• Foam because the sound waves will reflect back into the studio

• Foam because the sound waves will be absorbed into the foam

• Wood because the sound waves will reflect back when they hit a hard surface

• Wood because the sound waves will be absorbed when they hit a hard surface
