17.1: Mechanical Waves Notes
What is a wave?
• When ____________ is disturbed, ________________ comes from the ___________________. This
energy is in the form of a ________________.
• A disturbance such as a pulse or shock produces a wave.
– These disturbances are many times repeated or periodic, such as a guitar string being struck.
This makes the wave continuous.
ALL WAVES TRANSPORT _______________________!
Mechanical Waves
• Disturbance in matter that _________________ ________________ from one place to another
• Created when a source of energy causes a ________________ to travel through a medium.
• Requires a ___________________ to travel through.
• ______________, ______________, and ________________
• Classified by the WAY they move through a medium.
3 Main Types of Mechanical Waves
• _________________________________________
• _________________________________________
• _________________________________________
Transverse Waves
• Wave that causes the _____________________ to ________________ at _____________ angles to the
direction in which the wave travels.
• The wave carries energy from _________ to _________
• The _____________ point of the wave is the __________________.
• The _____________ point of the wave is the __________________.
• Examples of Transverse Waves
• ___________ created when rock is thrown into _______ Draw and Label a Transverse Wave
• Rope tied to a tree
• Motion of a plucked guitar string
• ___________ waves…also called electromagnetic waves
• Secondary earthquake waves
• Come after Primary Wave
• Cause the ground to roll
Longitudinal Waves
• Waves in which the _________________ of the ________________ is ___________________ to the
direction the wave travels.
• An area where the particles in a medium are spaced __________ together is called a
__________________.
• An area where the particles in a medium are _____________ _______ is called a
_______________________.
Draw and Label a Longitudinal Wave
• Examples of Longitudinal Waves
• ______________________
• Primary earthquake waves
• Shock waves from an explosion
Surface Waves
• Wave that _______________ along a ________________ ____________________ two media.
• __________________ of the medium ___________________ a ________________________ motion.
• _______________ waves are the most familiar kind of surface waves.
