2nd. Colored rings of Newton, observed by reflection, by refraction. Law of the diameters; these vary in absolute length for different colors. Variously colored rings with white light. Reflected rings with a white spot at the center.
The theory of the undulations does not apply merely to theses phenomena. Explication of the laws of reflection and refraction. Definition of polarization in the system of waves. Elementary application of double refraction and the polarization which accompanies it in uniaxial crystals when the face of the crystal is parallel to the axis, and the plane of incidence normal or parallel to this axis.
Chemical and Calorific Radiations.
Chemical and calorific radiations are subject, like luminous radiations, to the laws of reflection, refraction, dispersion, double refraction, polarization, interferences.
Lessons 35–36. Revision.
Considerations on the totality of the subjects of the course.
MANIPULATIONS IN PHYSICS.
The practical exercises which constitute the subject of this programme will be performed in part by the pupils under the direction of the professors and répétiteurs, in part by the professors and répétiteurs, with the coöperation of the pupils.
