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:

Refraction is the bending of light that takes place at a boundary between two materials having different indices of refraction. Refraction is due to a change in the speed of light as it passes from one medium to another.

The boundary is the region where one medium meets another medium.

At a boundary, an incident ray can undergo partial reflection or, in certain situations, total internal reflection.

No bending of the incident ray occurs if it strikes the boundary along the normal.

The incident ray is the ray approaching the boundary. It strikes the boundary at the point of incidence. The refracted ray is the ray leaving the boundary through the second medium.

The reflected ray is the ray undergoing partial (or total) reflection at the boundary. The normal is a construction line drawn perpendicular to the boundary at the point of incidence.

The angle of incidence (i) is the angle between the incident ray and the normal. The angle of reflection (r) is the angle between the normal and the reflected ray. The angle of refraction (R) is the angle between the normal and the refracted ray.

Particle of Light Theory
 - proposed by Newton
 - light travels in a straight path

Wave Theory
 - proposed by Christian Huygens
 - light properties are mostly wave light
 - diffraction and interference

Photoelectic Effect
 - by Einstein
 - quantum electronic phenomenon in which electrons are emitted from matter after the absorption of energy from electromagnetic radiation such as x-rays



Quantun Theory
 - by Planck
 - quantize, cannot be broken down into smaller particles

Photons - energy from light
