Light waves are relayed through transparent or see-through materials, like windows.

Choose the best vocabulary word that describes when waves pass through or are sent forward through a medium (solid, liquid, or gas):

A sound engineer is working with a singer that is having a hard time maintaining an accurate PITCH. How can the engineer change the sound wave to fix this?

• Change the sound wave’s Intensity

• Change the sound wave’s frequency

• Change the sound wave’s volume

• Change the sound wave’s amplitude

The sound engineer received a recording of a new artist, but the artist isn’t singing with enough volume to hear their voice over the instruments.

How can the engineer fix this issue?

• Increase the sound wave’s frequency

• Increase the sound wave’s Amplitude

• Decrease the sound wave’s Refraction

• Change the sound wave’s crest

Sound waves are created by the ______________ of particles in different mediums (solids, liquids, gases)

• vibrations

• compressions

• rarefactions

• electromagnetism

Which light wave will appear the brightest?

• #1 because it has a higher amplitude

• #2 because it has a lower amplitude

• They will be equally bright

• Light waves do not indicate brightness

Which wave model shows the structure of a Sound Wave?

• The Longitudinal wave because the wave travels parallel (side to side) from the source of the vibration

• The Longitudinal wave because the wave travels perpendicular (up and down) to the source of the vibration

• The Transverse wave because the wave travels parallel (side to side) from the source of the vibration

• The Transverse wave because the wave travels perpendicular (up and down) to the source of the vibration.
