Refraction of Water

The end is near and I'm almost a fourth quarter senior! how crazy! soon, I'll be blogging about physics in college life! hahaah nott. my followers dont appreciate me enough.. in this picture above you see a the new girl scout cookies box, called Thank You Berry Much (my new favorite, go order yourself some doc! :)), and a glass of water. But, can you see the entire box of cookies clearly? I think not! This is because of REFRACTION! cool yea?! Refraction is the change in direction of light as it passes from one medium to another. In other words, its the change in speed and direction of light. the speed of light is slower through water (than air) which is why the image we see is "bent" or distorted. The way the glass is shaped can also affect the distorted image of the cookie box because the glass isn't flat but round.

Self Reflection

Doc, since youre reading this..is it a requirement that i take the AP Physics exam, because I am dreading it!! ahh, baseball season is brutal huh? To all my faithful followers doc is the smartest man who unfortunately has to deal with me everyday :) So, this picture was taken awhile ago when i was getting ready to go out with some of my girlfriends. And it is very relevant to what we're learning this week, light reflection and mostly the physics of mirrors. First, you must learn the terminology. If we're looking at this picture, I am the object and the reflection of myself is the image. There are also many light rays that're involved in what you see in a mirror. For example, the color or light from my dress seen in the mirror has a path of light that begins at my dress to the mirror to the camera lens (that took this picture). Since there is only one mirror in this scenario, the distance of the object, myself, from the mirror is equal to the distance the image, my reflection, is from the mirror.
