# What things did I learn from the article

We need to set control criteria and give students a clear understanding of the problem they face because there is no better way for them to understand and control their actions and thoughts. After this article, we should not be subjective about school violence, even if our country has low rates on this issue but we are not subjective to avoid the unfortunate incident on the rise. Again, it is the loss and the mistake of every person on how to think and be subjected to the serious consequences of school violence can cause. So we need discussions and take preventive measures to minimize the occurrence of these events and to make society in this country more and better.

Destructive interference:
When two waves interfere together, they have the same amplitude in opposite direction. If there are more than 2 waves interfering, the situation gets a little more complicated. when the two waves meet in this following example, they collide and go apart as crests and troughs. when two amplitude has opposite signs they will also form a wave with a lower amplitude. the following diagram shows two pulses interfering destructively. Again, they move away from the point where they combine as if they never met each other.
The shape of headphone and the material they’re made from can physically block certain sound waves is 180 degrees, it means that the wavelength is zero, which results in silence.
Constructive interference:
Constructive interference occurs when wave come together so that they are at the same point with each other. Means that their movement at a given point are in the same direction, due to the result of the amplitude at that point being much larger than the amplitude of an individual wave. After the collision, the wave came back to the original point. In conclusion, due to the Constructive inference, we were able to find a significant increase in amplitude

# Pursuit of Happiness Reflection

To be honest, This is one of the most favorite films on my list, I really enjoy it because of the motion they bring to me. They gave me the feeling of how broke the actor was, How hard he used to through all the hardship moment of his life. The films show the feeling the most dramatic change through the time in his life. He was broke, He was get stolen, his wife left him away, all of the most difficult things came to him at the same time, he was kicked out of his place, he was overnight at the train, he was a homeless, he lost everything, when He just got back some money to lives through some months, the bank took his money away, he broke again. The hardship things just came to his life like the waves, over and over, It seems like life doesn’t give him anything, instead, life takes away everything of him. The most powerful feeling I got from this firm was hurt, That feeling really touched my soul, It changes my mind in many ways, I changed the way I think about this life, the way I look at the homeless, and the way I respect people get hard times in there life. And it changed me too, I still have a better life than many people out there, so I need to stop complaining about my life. I learned how to stand up after hardship things in my life, I learned how to get happy, and learned to protect what I want to be.

# Thank you Ma’am Quick Write

The most acting I’ve ever done for someone was helping an old man walking under my umbrella through the street. I forgot to wear my coat so it was so cold but I still walk with him until going to his home. It was a long way because his house if far than my house and he is an old man so he walked really slow, but I didn’t get impatient for my acting. I feel like I did a great thing in this life, I don’t know why but I feel that I’m a kindness person at that time, the moment that old man smiled and said thank you to me.
