Solution

Dear Student, An electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies. The spectrum of white light comprises of 7 colours called VIBGYOR. The components of white light after a glass prism has separated them can be recombined after passing through another prism placed upside down. Regards
