Reviewing Waves
Mechanical waves have to travel through….
•A fulcrum• Empty space•Water only•A medium
Electromagnetic waves can travel through…
•Gases, solids and liquids only• Empty Space only•A vacuum only•A medium and a vacuum
What is empty space?•Underneath you bed•Where there is no matter• Gases, solids and liquids• The air around you

this point you’d
be a vegetable

Longitudinal waves need to vibrate matter in order to move
so all are examples of…• Electromagnetic •Mechanical waves• Transverse waves•Ocean waves
Longitudinal waves move __________ the direction the
wave is moving.• Closer to • Away from • Perpendicular to• Parallel to

The highest point of a transverse wave is called…
• Crest• Trough• Compression• Rarefaction
The lowest point of a transverse wave is called…
• Crest• Trough• Compression• Rarefaction
What is wavelength?
• Distance from crest to crest• Distance from middle of wave to crest
or middle to trough• Number of waves that pass through a
point in a second•Middle of a wave
What is wave frequency?
• Distance from crest to crest• Distance from middle of wave to crest
or middle to trough• Number of waves that pass through a
point in a second•Middle of a wave
What is amplitude?
• Distance from crest to crest• Distance from middle of wave to crest
or middle to trough• Number of waves that pass through a
point in a second•Middle of a wave
Which of the following is NOT an example of a transverse wave?

The color white ______ all colors while the color black _______ all colors.
• Absorbs, reflects• Reflects, absorbs• Absorbs, absorbs• Reflects, reflects
Light gets reflected at ________ angle it hits.
• a higher• a lower• a different • the same
The bending of a wave as it passes from one medium to another is called…
• reflection• refraction• diffraction• interference
When an object causes a wave to change direction it is called…
• reflection• refraction• diffraction• interference
When two waves collide or run into each other it is called…
• reflection• refraction• diffraction• interference
