prisms

I used to own a prism which split light into different colors. The prism works via Snells law. A ray of light enters the prism and it is refracted inside and seperated into the various different colors that are released from the other side of the prism. The prisms were used to show that regular light was not colorless but simply required a tool to demonstrate the various colors. There are several different types of prisms triangular, abbe, pellin-broca, amici, and compound. I hope we get to use

a mass can create waves

As a life gaurd I have the responsibility to work in the morning at times. This means coming in to school at 5:45 am and guarding for people who decide to do laps. Recently a gentleman came in and was somewhat rude and impatient. This is something I really don't care about to much but he was a rather large fellow amd was the first one to enter the still pool via a canon ball near the gaurd chair. After I got over the immediate displeasure at being soaked I noticed how in the pool his mass had c

magnetic waves on the sun

Recent studies by nasa try to explain why the corona is so much hotter than the surface of the sun. The corona is a layer of plasma traveling millions of kilometers into space from the sun and can reach temperatures of 2 million Celsius over 20 times hotter than the surface of the sun itself. Recent studies have reintroduced previously ignored magnetic waves called alfven waves which in theory drive solar wind through the outermost layers of plasma and heat or accelerate it. Recent studies show

fun stuff to do with magnets

I was bored at my grandfather's house since he only has basic tv which I no longer watch. so I wandered around his house to see of he had any cool stuff. My grandfather loves metal detecting and finds magnets to be very interesting. I found several neodymium magnets in his study and decided to see what I could do. He has an iron deficiency and has cereal that is slightly infused with iron. Firstly no it was not magnetic. But when I crushed some into a fine dust I was able to separate iron from t

amp of a tsunami

I read recently of tsunami that occurred in 1958 that occurred in lituya bay Alaska. This accrued when a 30.6 million cubic meter rock fell around 3000 feet into the water below generating an enormous wave that had a crest of 1720 ft above sea level. It removed all vegetation up to that point and is by far the largest wave ever recorded.this wave was so powerful maps of the area had to be altered due to the power of this titanic wave.

railgun

I saw a cool video once on the discovery channel. It was a special on a newly made weapon by the United States military. It is a large cannon type weapon on large battleships. It is interesting in that it uses magnets to launch shells farther and faster than had it been used with gunpowder. It works by having two magnet rails in parallel that have the magnetic field pointing down the barrel towards the target.

car crash

my mother once witnessed a very impressive but altogether terrifying car crash several years before i was born. it late on a friday and my mother was driving down the highway with the only other driver in sight being a large eighteen wheeler that was about 30 meters ahead of her. a drunk driver had somehow made it two miles down the mostly empty road and was going far above the speed limit of 60 mph. the truck was many times larger than the small four seater and even though it had a greater spee

potential and kinetic energy: snowboarding

earlier this winter me and my dad went some ski resort up in Canada go snowboarding which was actually very fun and unlike most of my other posts there were no unfortunate falls to note. however when snowboarding the lack of nearly any friction makes the transfer of potential energy to kinetic very noticeable. after you reach the top of the hill via lift there is a very high potential energy and since the hill was enormous so was my potential energy. As i travel down the hill i am going faster a

physics of a swingset

when i was ten years old and my sister six me and her often went to the park to play as kids do. the swings were our favorite since they went the fastest after. the swings work by increasing your momentum back and forth by kicking your legs and increasing energy within the swings constantly until it reaches a comfortable level for the person in the swing. at either highest point of the swing the potential energy reaches its peak and many children including my sister and i t the time like to jum

impulse of a flip turn

i have not posted a blog on this site since the very end of last quarter and since then the swim season has started and almost come to an end. weeks ago we learned the impulse momentum theorem which states that an impulse acting on a system changes the systems momentum. a good example of this would be somthing in swimming called a flip turn, for those unfamiliar with the concept a flip turn is done at either end of a pool during a race to turn around and continue. during a flipturn the swimmer

all actions have and equal and opposite reaction in swimming

As a swimmer you must be proficient at several key pieces, at least two strokes, diving and flip turns being the most notable to the time one receives in a race. Equal and opposite reactions are major points of a stroke, a swimmer kicks in the water the swimmer is pushing against the water which in turn propels him forward and the stroke (arms) are use to push against the water which further propels said swimmer. When the swimmer starts the race is also key as a good dive can give you important

every time i almost died is because of physics

During my relatively short life I have fallen many many times , several come to mind as to be the most notable and all of which are due to gravity. One of these is when me and my friends were riding our bikes and their was a ledge separated from another with about an eight foot drop. I assumed that I could travel fast enough to cross the gap. keep in mind this was two years before I leaned about trajectory so a peddle and peddle and go straight off and immediately started to travel downward.

an object in motion...

During the catapult project after my partner had to go home I decided to is my power drill to make some necessary holes in the wood that formed the base. So I went about it and I felt like I forgot something but shrugged it off. I learned about five seconds later that what I forgot was the clamps for the wood. The wood spun around and hit me right in the Charlie horse, an area behind the thigh that if its hit buckles which normally makes people fall. Now had my leg not stopped it under a circums
