when 16 year olds meet physics

physics test today was... so hard it was funny.

it's the kind of test where you look at the question, and think...
"what the sh*t?!?!"

let me give you some examples of the questions and some answers. these are based on what people have told me, and what i remember of what i wrote after the test.

Q: movies often use a type of glass known as "sugar glass" in their stunts. "sugar glass" looks and shatters the same way as real glass, but does not cut an actor when he/she smashes through it. how would you determine whether or not a solid is "real" glass, or "sugar" glass. you are not allowed to touch or break the solid.
Nigara wrote: shine a light through it. if it transmits, it is real glass. if not, it is... err... not real glass.
i wrote: you shine a light through, then you measure the angles. then ah, you calculate the refractive index. then you compare. then you see. if good, then real lo. if not, then not lo.
william wrote: lick it.

Q: myopia, or short sightedness, is a condition of the eye. what type of lens would you use to rectify this?
alfred reads the question, then thinks for a while. and then he slowly takes off his spectacles, and stares at them intently for a while. *thinks* how come one side is convex, and the other side is concave?

Q: if the earth had no atmosphere, and you were to look up at the sun, what would you see?
i wrote: if the earth had no atmosphere, and you were to look up at the sun...... you would not be able to see the sun. *pauses and thinks for a while* even if you were able to see the sun, it would blind you and burn you and you would die.
jiayan wrote: you would see red.

Q: complete the ray diagram to determine where the image will be formed.
nigara: HAH, FREE MARK!!
kim: erm... nicole, borrow rubber? x1999
mike: *draws for a while* i think i need more paper.

Q: in order to achieve a more natural colour in underwater photography, what colour filter should be used?
mun tsin: *she's the smartest girl in our year* you need to use either a red, orange, or yellow filter in order to absorb blue and indigo light to achieve a more natural result. *sounds so pro*
sarah: you need a blue or violet filter to suck the bad colours out.
kim: you need to either use a filter that absorbs blue and violet light, or one that doesn't.

Q: calculate blablablablablabla.
nigara: -9.23
kim: 17.1
william: 0.64
-______-. same question, same formula. and william realizes after the test..
"OMG.. MY CALCULATER WAS ON RADIANS. OMG. OMG. OMG."

smart one.

we're all going to do so well in this test. i can feel it.

i screwed my physics test up too. i wrote i could see rainbow-looking-sky at first, but i changed it to red and blue sky. -for the atmosphere question. n i didn't realise that the prism for dispersion was actually upside down. lolx.
