Like some others, I personally cannot sleep unless it is completely dark in my bedroom. However with the placement of my bed in a dark area of my room, I'm surprised to find that I cannot sleep because there is still light shining on my bed. But why is there still light if the window in my bedroom is behind my bed, next to a wall? Shouldn't the light be blocked by the barrier? No! The light from the window still shines on to my bed, despite the wall barrier and placement of the bed and window, because there is a diffraction of the light waves. Diffraction occurs when light waves move past t

This week at The Lilac Festival, my mother and I experienced loads of different noises all at the same time. With loads of security, we heard lots of sirens passing us, creating the Doppler Effect. The Doppler Effect is the shift of frequency of a wave when a source moves past. As a source with sound, such as a police car or security car, moves towards you, the frequency is smaller, which creates more of a high pitched sound. While moving, the frequency then begins to increase and after it passes you, the frequency is larger, making a lower sound. To the human ear, the frequency increase

In today's news, young physicists at Irondequoit High School have miraculously calculated the acceleration due to gravity, g. These young physicists found their data by experimenting with a ball. First, the students dropped the same ball three times, recording the time it took to travel to the ground. They recorded their data in an organized table to keep track of each trial. The Physicists then took the average of the different trials of times and plugged the average into the equation d=vit+1/2at^2. By plugging the data into the equation, they found that the acceleration due to gravity was 10

Heyyy we agree about the boring chemistry part Yay physics

Hey girllll, I dig your paragraphs. I like New York City too. I'll see you tomorrow...It's keys.

My name is Hannah and I am a senior student who is taking physics this year. I am an only child which is why I have a weird and special relationship with my dog, Sydney. My favorite things to do are baking, singing, dancing and being in musicals. I am a music nerd and have been dancing since second grade and have been in 7 musicals. I am very short and small but am full of energy and very enthusiastic. I am taking physics this year because it was the next science to take that wasn't an AP and I didn't want to drop science overall. I am not very good at science in general, but the topics an
