Interference 🌊

Do you know what constructive and destructive interference is?  Well if you don't know I can tell you. 

Constructive interference is when the crest of a wave interacts with the crest of another wave to increase the amplitude. 

 Destructive interference is when the crest of a wave interacts with the trough of another wave to decrease the wave. 

 

As you can see the difference is that constructive interference is for increasing the amplitude and destructive interference is for decreasing the amplitude. 

-an example in my life is;

   When I had a problem and my friend was "helping" me, instead of helping me she said things that made my problem worse. So it decreased the point of me showing I didn't do something wrong. 

-an example of constructive is; 

  When I had a meeting at a school and I had to dress up. Well I put something good on so I could impress them. This increased my image to look good and professional. 😌

   

No Effect 😱

Something that I think should be affected by another thing is a glue stick. We use glue to stick things together... But!! Why doesn't the glue stick into the inside of the bottle? It doesn't  stick inside the bottle because the inside of the bottle has a speacial material that doesn't get sticky with the glue. 😌🤓👏🏼🙌🏼

Standing Waves 🌊

Today we did a lab called " Standing Wave Lab". In this lab we stretched out a spring and looked for the frequency, the wavelength, and it's speed. After this lab I learned that waves with different shapes have different speeds. But also tht the waves amplitude doesn't affect the waves speed. 

Electricity Generator

I'm really interested in the Hydro Electric Power generator. I chose this generator because I find it I interesting how water makes a turbine turn to make us electricity. This generator works by a dam blocking a body of water until the fills up then it releases the water which makes a turbine turn.  Its one of the better forms of electricity generation because the air is goin to be clean. One thing that is bad bout this form of electricity is finding a location to install a dam. This is a pro elm because you can't put a dam where there is a river near a city. Cuz when the dam fills the city can get flooded. But really, anywhere that there is a big body of water you can install a dam not next to a city. 😊🌊

Circuit Diagram ✏️📊👻

In a circuit diagram instead of drawing the exact thing we use symbols. We use symbols because it is easier to represent what we are trying to show. When using symbols it is easier because it takes less time to draw what we want to show. What is bad of using symbols is that if someone who is looking at it doesn't know what each symbol means then s/he will not know what is goin on in the diagram. 

But in conclusion if you want to do a circuit diagram it is easier to use symbols and to help others u can make a key where you have the symbols drawn and what each represent. 🤓✏️
