Year 11 Physics – Light lab

September 2, 2019:

Year 11 students at Assumption College English Program investigate some properties of light. Using light boxes and coloured filters or slides, the students examined the additive colour spectrum. Complementary colours were produced by combining 2 primary additive colours.

Students also determined the grid spacing of a diffraction grating. By using the constructive interference equation, the spacing of the grating (d) could be determined after measuring the angle between the central maximum and the first order constructive interference fringe. The wavelength of light was determined from the specification of the laser used in this experiment.
