Another Scribe...

Hey, another scribe again (sigh) :(. first things first, we started by going over the Nature of Light questions #13 through 15 which would be in the post previous to mine in the slide Ms. Kozoriz made.
After that, Ms. K made us read The Photoelectric Effect and the Wave-Particle Duality section of our PINK booklets. Here’s a short summary on the back of the book that goes over some of the main points we read about in class:

A photoelectric effect, talks about the discharge of electrons from a metal surface when it is exposed to electromagnetic radiation, (we looked at an example of this on the internet).

The only way electrons are ejected from a metal is if the frequency of the radiation is above a particular minimum value which is referred to as the threshold frequency. This threshold frequency varies with every metal.

Albert Einstein proposed that the energy of light and other forms of electromagnetic radiation is concentrated in discrete bundles of energy called photons. He stated that the amount of energy in each of these bundles was a discrete, fixed amount that depended on the frequency of the light.

When light passes through a medium, its behavior is explained best using wave properties. When light interacts with matter, its behavior is more like that of a particle. Light has a Wave-particle duality.

And don’t forget…

The Principle of Complementarity, this states that “to understand a specific experiment, one must either use the wave or the photon theory but not both”. In general the wave theory best explains the behavior of light when it passes through space or a medium. When light interacts with matter, its behavior is more like that of a particle.

The last thing we did was watch Ms. K play with some dog on a skateboard on a sting for the rest of the period.

The next scribe will be.......i don't know.
