| Description | In this paper an experiment studying a colour and a spectrum of light produced by a digital projector is presented. The colours and spectra were taken with a digital camera. The simultaneous study of colour and spectrum simplifies the understanding of the relationship between the colour and spectrum, additive mixing of colours, concept of complementary colour etc. The experiment is very attractive for students. It is also very easy due to the use of the standard digital projector. |
