A Range of electromagnetic radiation of all possible frequencies obtained by passing light through prism is called a Spectrum. every light that can pass through the prism or spectrum can obtained seven colors. the radiation of every light has its own wavelength . and also passed rays bend to has own extent , depending on its wavelength . the shorter wavelength bend more than larger wavelength . the light obtained different colors or range of wavelength on passing through a prism..                                                                                                                                                                                                                                                                                                                posted by Malak Ghayoor
