Spectrum and electromagnetic radiations:
What is a spectrum?
Ans: A spectrum is a group of wave lengths or frequencies.
What are the electromagnetic radiations?
Ans: Electromagnetic radiations are characterized by oscillating electric and magnetic fields perpendicular to each other and also perpendicular to the direction of propagation. All these radiations travel with the same speed,that is 3 x 108m/s2.
