Spectral Plus

The Spectral Plus demonstration set is designed for easy visualization of the basic light and colour principles. By using red, green and blue light-emitting diodes (LEDs), filters of different colours and gratings, it is possible to demonstrate additive and subtractive colour mixing, light diffusion, absorption and diffraction. By using the spectroscope students can analyze the light emitted by the different light sources, understand the difference between continuous and bright line spectra and understand the general white light source.

Colour and colour vision are very interesting parts of physics for students since they get in touch with the principles of everyday life.

Advantages of this set:

• light effects – experiments with light have strong motivational potential
• visibility – demonstration of creating different colours
• easy to manipulate – simple colour adjusting, simple turning on and off of light sources
• safety – the tool does not use high-voltage
