Waves Review part 1

A student is using a color filter in his experiment. What would be true if she was using a blue color filter?

• The color filter will only absorb green light.

• Objects seen through a green filter will look blue if the objects absorb blue light

• Non-blue objects will appear black because other wavelengths are absorbed by the filter

What happens when a sound wave touches an object?

• The sound wave is refracted by the object.

• The sound wave is reflected by the object, causing an echo

• The sound wave is absorbed by the object, increasing volume.
