   It was a calm November morning in Nazare located in Portugal. A man named Garrett McNamara, who is a surfer was thinking shall he go to surf that day or not. His decision made a mark in the whole world. He decided to go, and together with that, he set a new world record. He surfed the highest wave. The wave was approximately 90 feet tall. Amazing. Well, for it to be more amazing, the whole thing was caught on tape. The video is now on YouTube. The video is only 25 seconds long, but it has the whole thing down.
      When I read this article for the first time, I taught this cannot be true, but then I saw the video and started to believe. But, when I didn't believe, it is not that I taught the media was exaggeration, but that the whole thing is made up. I cannot picture myself standing in front of a 90 feet tall wave. Surfing on one, I will never imagine, even now when I read this article. Congratulations to this man.
Here is the video:

Water waves lab

        In science class we did a lab and we explored a simulator to investigate how do water waves travel and the effects of it.
 What have I learned from the simulator is that the higher the frequency or the speed of the drop, the wave is shorter and the wavelength is shorter.You can then guess that the lower the amplitude, the higher the wave is and the wavelength is longer.
         When the amplitude or the size of the wave is lower, the waves are smaller. That small that they disappear in a certain level of amplitude. This means that the wavelength is 0. When the amplitude is higher the waves were, of course, higher much higher. The wavelength was again, obviously bigger.
          To conclude, the waves are mostly affected by the frequency and the amplitude of  the water. If the drops were smaller than the waves are smaller. The bigger the drops, the higher the waves are. For the frequency, when it is higher, the waves are bigger. When the frequency is lower, the waves are smaller.
