Ans: The electromagnetic spectrum shows the significant grouping of electromagnetic waves. The scope of frequencies and frequencies is momentous (striking). The division line between certain rundowns is particular, while different classes cover. Microwaves envelop the high-recurrence segment of the radio segment of the electromagnetic range. The part of the electromagnetic range discernible to the natural eye is known as the noticeable range. This scope of frequency is explicitly called obvious light. The scope of frequencies that the natural eye can distinguish is from 380 to 700 nanometers.
