Hi there, people of the earth!!! On this site, you will find a weird but wonderful collection of FUN Physics. Physics is often regarded as the "Dreaded Subject". The stereotypical view of a physicist is one standing by a borad filled with crazy symbols and numbers. This site are meant to show the other side of physics.....both interesting and funny. Cool!!

Hi! My beautiful name is Ellaine G. Dela Cruz. I'm one of the student of the star section, DARWIN! Yehey. Clap clap clap. By the way, I like listening to music, watching tv, surfing the net, sleeping and last but not the least, eating! Yehey. I don't like making a lot of assignments(btw, who likes it?)

If you want to know me better, here are my contact details:

Lens

  - glass or other transparent substance so shaped that it will refract the light from any object, and form a real or virtual image of the object.
  - series of tiny refracting lenses, each of which refracts light to produce their own image.

Converging Lens

  - lens which converges rays of light which are traveling parallel to its principal axis.
  - can be identified by their shape; they are thicker across their middle and thinner at their upper and lower edges

Diverging Lens 
  - lens which diverges rays of light which are traveling parallel to its principal axis
  - identified by their shape; they are thinner across their middle and thicker at their upper and lower edges

Refraction Rules for Converging Lens

1. Any incident ray traveling parallel to the principal axis of a converging lens will refract through the lens and travel through the focal point on the opposite side of the lens.
2. Any incident ray traveling through the focal point on the way to the lens will refract through the lens and travel paallel to the principal axis
3. An incident ray which passes through the center of the lens will in effect continue in the same direction that it had when it entered the lens.

Refraction Rules for a Diverging Lens

1. Any incident ray traveling parallel to the principal axis of a diverging lens will refract through the lens and travel in line with the focal point (i.e., in a direction such that its extension will pass through the focal point).
2. Any incident ray traveling towards the focal point on the way to the lens will refract through the lens and travel parallel to the principal axis.
3.An incident ray which passes through the center of the lens will in effect continue in the same direction that it had when it entered the lens
