Waves Review

A wave transfers:

• matter
• water
• energy
• particles

A wave that moves in a side to side pattern is a

Ex- sound wave

• electromagnetic

• standing

• transverse

• longitudinal

A wave that moves in an up and down pattern is a

Ex- water wave

• sound
• water
• transverse
• longitudinal

The distance between the crest of a wave and the crest of the next wave is:

• 3mm
• frequency
• amplitude
• wavelength

The number of complete waves that pass a point in a certain amount of time is:

• speed
• frequency
• amplitude
• wavelength

A wave changes speed as it enters a new medium causing it to bend.  This is an example of:

• reflection
• refraction
• diffraction
• interference

the highest point of a transverse wave

• crest
• trough
• compression
• rarefaction

the lowest point of a transverse wave

• crest
• trough
• compression
• rarefaction

Why does sound travel faster through a solid object than in the air?

• The atoms in the solid object are farther apart than the atoms in the air.
• The atoms in the solid object are closer together than the atoms in the air.
• The atoms are smaller in the solid object than the atoms in the air.
  
• The atoms are larger in the solid object than the atoms in the air.
  

How are electromagnetic waves different from other waves?

• They have very short wavelengths.
  
• They transmit energy instead of matter.
  
• They can travel through a empty space.
  
• They can change direction by reflection when they strike an object.
  They can change direction by reflection when they strike an object.
