this week was the last week of the first semester/2nd quarter. Which means, for us seniors, the hardest part of the school is over and we just need to worry about keeping up with what we had been doing. this also means that i still need to pay attention to physics properties that occur in our daily lives. First of all, i found it interesting that when you hear radio or tv noise through a phone, you can clearly see the lag. this is clearly because the sound waves are transmitted as radiowaves for phones and that is not fast enough to make is lag-free. i am guessing that the farther you are away from the sender, the more lag it will be and that is physics right there.
