Product Code : EL-PL-13526
Jlab Export is a leading Optics Set OG1, Geometrical Optics Manufacturer,and suppliers in India
Optics Set OG1, Geometrical Optics (code EL-PL-13526) is a boxed student set for 20 experiments on light rays, from reflection in plane mirrors to refraction, total reflection, lenses and colour mixing. An experimental lamp behind slit diaphragms supplies the ray beams. JLab builds the set in Ambala, India, and the OG1 student workbook and teacher’s manual come with it in electronic form.

The 20 Experiments
Reflection: light rays and beams, reflection on a plane mirror, the virtual image in a mirror, tilted mirrors, and the focal point and characteristic rays of a concave mirror. Refraction: refraction, the planar-parallel plate, refractive index at the air/water interface, the angle of total reflection, the total reflection prism and the optical fibre. Lenses: focal point and characteristic rays of a convex lens, the apparent focal point of a concave lens, and lens combinations. Colour: decomposition of white light, additive and subtractive colour mixing, and crossing light beams.
Total Reflection and Subtractive Colour
A ray entering the curved face of the semi-cylindrical body along a radius passes unbent to the centre of the flat face. As the angle of incidence grows, the ray leaving into air bends further from the normal until, past the critical angle, all of the light reflects back inside. Read from the angular disc, that angle gives the refractive index, since n = 1/sin C. Through the yellow and cyan subtractive filters together, only green light passes.
