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.
