At the beginning of the class, Mr. Vincent gave us a quick review about how to calculate Velocity and distance. He also provided some formulae and examples that could be useful in some ways. Vector requires magnitude and direction while Scalar doesn't. An example of a scalar is speed and an example of a vector is displacement. After that, we did an activity called "Creating a pirate treasure map" where we are asked to make and design our own pirate treasure map using vectors. We didn't able to finish it today so we will continue it tomorrow.

At the beginning of the class, we went over the answers in NOL2 problems #'s 1-12. Mrs. K posted the answers in this blog by the way so if you don't get a chance to copy them, be sure you do! We then watched couple of videos related to Wave Theory.

A new formula was introduced to us and said to be useful:

wavelength = (x)d/L

wherein:
x is the distance between adjacent nodal lines on a screen.
d is the separation between the slits.
L is the perpendicular distance from the slits to the screen.

A worksheet was given to us related to this formula for practice. Be sure to answer it.

At the beginning of the class, we went over our tests about Nature of Light Part 1. Mrs. K gave us each and every detail from it. Then, Mrs. K introduced a new lesson entitled Nature Of Light Part 2: The Wave and Particle Models of Light. We then highlighted some important details in the first topic and learned 4 theories that are developed ages ago.

We were given two handouts:
Unit Conversion (for conversion practice.)
A worksheet that you are asked to explain how each theories (Tactile, Emission, Particle, Wave) describes light. You are also asked to draw a picture at the back of it. (It needs to be handed in on Monday! Be sure to do it!)
