Interference

      Interference is the reaction when more then one wave is in a medium. The different between constructive interference and destructive interference is that in a constructive interference the crest of a wave is super positioned with the crest of another wave to increase the amplitude. And in a destructive interference is when the crest of a wave is super positioned with the trough of another wave to decrease the amplitude.


                    

     

Standing Wave

    Today in class we did standing wave, we basically swing one end of the spring back and forth over and over again along the floor. Which the result of doing that is called a periodic wave. I learned that standing wave is a pattern of a wave that looks stationary or not moving.

Electricity Generator

     I thing that the solar system is interesting. It'is clean, and is renewable. 
 The bad thing is that is not on demand, and it takes a lot of space.
A solar power generator uses the sun's energy to create electricity. Unlike a photoelectric panel, which converts sunlight directly into electrical current, a solar thermal generator uses the sun's heat to create electricity.

Simple Harmonic Motion

I would know when something is simple harmonic motion by the way it moves if the object is moving back and forth then that will be simple harmonic motion.

Ex.
this is simple harmonic motion because is going back ad forth.




this is simple harmonic motion because as you see is going back and forth.




when you touch the strings from a guitar the go back and forth, there for it's simple harmonic motion.
