A spectroscope is an optical device that could be used to produce and observe a specific portion of spectrum of light or radiation from a source. A compact disc (CD) can be used to make a simple spectroscope. The following video link (from Arvind Gupta's website) demonstrates how to make it.

#This radiation can be thought of as waves of different wavelengths. The waves are not of material objects but travelling waves changing electric and magnetic fields. Different wavelengths are associated with different energy levels and different kind of radiation.

#Repeat the experiment but this time use only one torch. Now keep placing different colour sheets tightly over the torch beam adding them one by one. And find out the colour of the beam that comes through. We should find that we get similar combinations as when the beams are mixed – only the light will be weaker.
