    I have to perform a project.
I have an idea of performing interference with polychromatic light(ie., White light)
Can anyone suggest me the sources from where I can get the white light.
                                                      (or)
Can anyone suggest me some other attractive project (which is very economical) in physics and chemistry??

Any white light bulb will do.

How about those white light tube used for table lamps?
