Wave

a disturbance that transfers ENERGY without transferring matter.

There are two types of waves:

1.) Mechanical waves: require a medium (matter) to travel.

2.) Electromagnetic (EM) waves: do NOT require a medium to travel.

Multiple Choice

What type of wave must have a medium to vibrate?

• Mechanical
• Electromagnetic
• Infrared
• Radio

Mechanical Waves

a. ) Transverse: particles move perpendicular (+) to the direction the wave travels.

Ex: ocean waves

b.) Longitudinal (compressional): particles move parallel (=) to the direction the wave travels.

Ex: sound waves

Multiple Choice

What do we call a wave where the particles move back and forth perpendicular to the direction the wave travels?

• transverse

• longitudinal

• sound

• p-wave

Multiple Choice

What type of wave moves by pushing together and spreading apart in a parallel direction to the way the wave travels?

• longitudinal

• transverse

• ocean

• radio

Multiple Choice

What type of wave is this?

• Transverse

• Longitudinal

Characteristics of Waves

Characteristics

Transverse waves:

Crest: highest point of a wave

Trough: lowest point of a wave

Longitudinal waves

• Compression: region where particles are closest together

  
  

• Rarefaction: region where particles are farthest apart

Multiple Choice

How would you describe the movement of a longitudinal wave?

• Up and down

• Back and forth
