PSU Base LEDPSUB LED Array

This versatile LED Array from PSU Base enables students to investigate the link between wavelength and colour. The unit has 10x coloured LEDs plus a white LED fitted into a vertical steel tower. There is a selector switch that allows each individual colour to be selected or all colours simultaneously.

When used with a diffraction grating the unit may be used to determine the wavelength of a particular colour of light. When all the colours are viewed through a diffraction grating, it allows the student to observe the effect that the changing wavelength has on the diffraction pattern. When used with colour filters, sweet wrappers etc., it allows a study of coloured light transmission.

• Fitted with On/Off switch
