"Colored sorcery" - mixing additive colors.

On 20.01.2011r. There were classes where we learned from what color it is light consists of a continuous white light and that the color of light is related to the length of the waves.

"after crossing light - light refraction on the boundary of two media.

On 13.01.2011r. took place the next class of mathematical sciences - natural sciences.


Topic Experiment 1: Effect of flying coins.

Observations: Observed
coin after adding water to the bottom of the vessel appears to be larger and located closer to the surface.
Conclusions: This phenomenon occurs
because rays reflected from the coin is bent during passage through the border of water and air. Experiment 2


Topic: Off tsp.

Observations:
spoon seemed to be the most articulated in the water, which was dissolved in 3 teaspoons of salt.
Conclusions: Light runs from the spoon, and before getting into the eye of the observer collapses the border between two media: water and air. It runs from the denser medium to rarer medium. Experiment 3

"Even light can not always moves in straight paths" - the right of the straight propagation of light.

On 21.12.2010r. classes were held in which we are acquainted with concepts such as law of reflection, refraction law, the law of rectilinear propagation of light, the right of total internal reflection. We have the following

Experience: Experience an


Subject: Light travels in straight lines.

Observations:
flashlight passed through two holes.
Conclusions:
light propagates along straight lines. Experiment 2


Subject: Shadows and midtones.

Observations:
wtyniku illuminate the globe on the screen appeared in its shadow, and after both of his reposed appeared midtones.
After setting the path between a flashlight, a disc of tissue paper globe, appeared on the globe shade.
Conclusions: This model is
phenomenon eclipse. Experiment 3


Subject: line of Light.

Observations:
stream water was luminous.
Conclusions: There was
phenomenon of total internal reflection of light.

Experiment 4
Topic: The phenomenon of total internal reflection in a prism.

Conclusions:
Depending on the setting rays of the prism direction is changing. We observe the phenomenon of total internal reflection of light.

Experiment 5
Subject: Reflections on the water surface.

Observations: light
collapsed on the border of two media.
Conclusions:
is a phenomenon of total internal reflection of light.
