Wavelength: The distance at any point on a wave to the same point on the next cycle of the wave.

All waves have amplitude. An amplitude is most of the time a distance or an angle. The way to measure amplitude is by the maximum distance the oscillator moves away from its equilibrium position
Resonance: An exceptionally large amplitude that develops when a periodic force is applied at the natural frequency]]> 2017-02-17 18:34:33 UTC https://padlet.com/bubba051904/p57wgtzrlb6i/wish/154668122 bubba051904 https://padlet.com/bubba051904/p57wgtzrlb6i/wish/154669665
Another thing that every wave has is frequency. Frequency is the number of complete cycles per second. The time it takes for 1 cycle to occur is called period. The unit of one second is called hertz. Something that completes one full cycle is equal to 10Hz.
Natural Frequency: The frequency at which a system oscillates when disturbed.
Periodic force: A repetitive force]]> 2017-02-17 18:40:44 UTC https://padlet.com/bubba051904/p57wgtzrlb6i/wish/154669665 bubba051904 https://padlet.com/bubba051904/p57wgtzrlb6i/wish/155578595 Cycles are a unit of motion  that repeat
Period: The time it takes for each complete cycle.
Oscillator: A physical system that has repeating cycles. Systems that oscillates moves back and forth.
Harmonic motion: Motion that repeats its cycles.]]> 2017-02-22 19:33:40 UTC https://padlet.com/bubba051904/p57wgtzrlb6i/wish/155578595 bubba051904 https://padlet.com/bubba051904/p57wgtzrlb6i/wish/155584699 In one complete cycle, a wave will move one full wavelength. To calculate the speed of a wave, you can multiply the frequency by the wavelength. You can also get the distance traveled and divide it by the time.]]> 2017-02-22 19:52:55 UTC https://padlet.com/bubba051904/p57wgtzrlb6i/wish/155584699 bubba051904 https://padlet.com/bubba051904/p57wgtzrlb6i/wish/155587133 Some types of waves are circular and plane waves.
Circular Waves: Moving waves that have crests that form circles around a single point where the wave first began.
Plane waves:  Moving waves that have crests in parallel lines.]]> 2017-02-22 20:01:10 UTC https://padlet.com/bubba051904/p57wgtzrlb6i/wish/155587133 bubba051904 https://padlet.com/bubba051904/p57wgtzrlb6i/wish/155592078 There are many wave interactions like refraction, diffraction, reflection and absorption.
Refraction: The process of a wave bending as it crosses a boundary between 2 materials.
Diffraction:The process of a wave bending through a corner or passing through an opening
Reflection: The process of a wave bouncing of an object
Absorption: What happens when an amplitude of a wave gets smaller and smaller as it passes through an object.]]> 2017-02-22 20:17:44 UTC https://padlet.com/bubba051904/p57wgtzrlb6i/wish/155592078 bubba051904 https://padlet.com/bubba051904/p57wgtzrlb6i/wish/155599318 https://padlet.com/bubba051904/b6m0nuuvfxd5]]> 2017-02-22 20:44:08 UTC https://padlet.com/bubba051904/p57wgtzrlb6i/wish/155599318 bubba051904 https://padlet.com/bubba051904/p57wgtzrlb6i/wish/156134508 https://padlet.com/bubba051904/8a2615azezoh]]> 2017-02-24 19:56:43 UTC https://padlet.com/bubba051904/p57wgtzrlb6i/wish/156134508 bubba051904 https://padlet.com/bubba051904/p57wgtzrlb6i/wish/156134974 A crest is a point on the wave where the displacement of the medium is at a maximum. A point on the wave is a trough if the displacement of the medium at that point is at a minimum.]]> 2017-02-24 19:58:28 UTC https://padlet.com/bubba051904/p57wgtzrlb6i/wish/156134974 bubba051904 https://padlet.com/bubba051904/p57wgtzrlb6i/wish/156136035 Waves are everywhere. Most of the information that we receive comes to us in the form of waves. You rely on waves to bring you music and TV. You can cook with waves, talk to others and see things all because of waves. Waves transfer energy in different forms, some are very useful, while others can be deadly.]]> 2017-02-24 20:02:56 UTC https://padlet.com/bubba051904/p57wgtzrlb6i/wish/156136035 bubba051904 https://padlet.com/bubba051904/p57wgtzrlb6i/wish/156136397 Without waves alot of our technology can't be here for our personal use right now like:
Radio waves

• TV and FM radio
• Direct line of sight with transmitter 

Satellite signals

• Frequency of microwaves pass easily through atmosphere and clouds

Infrared radiation 

• It is used for night vision and security cameras as Infrared Radiation is visible in daytime or night-time 
• Police use it to catch criminals, army use it to detect enemy

• The "medium" is the substance or material that carries a mechanical wave.
• Waves in the ocean are mostly generated by the wind moving across the ocean surface.
• Many waves cannot be seen such as microwaves and radio waves.
• One of the most important things to remember about waves is that they transport energy, not matter. This makes them different from other phenomenon in physics.
