People have been interested to study the visible light since the ancient era. Some form of energy was being produced by the tube that was penetrating the paper and causing the crystals to glow. The infrared part of the electromagnetic spectrum covers the range from roughly 300 GHz to 400 THz (1 mm – 750 nm). The electromagnetic spectrum comprises the span of all electromagnetic radiation and consists of many subranges, commonly referred to as portions, such as visible light or ultraviolet radiation. Therefore, it is not a new thing to learn. Some wavelengths are long. Various types of electromagnetic radiation sustain life on earth. Others are short. The factors, which differentiate them, are the interaction of matter, production of waves and practical application. The electromagnetic waves with the frequencies from one hertz to 1025 hertz are included in the electromagnetic spectrum. It is commonly said that EM waves beyond these … The energy produced is not enough to break the chemical bonds or ionize molecules or atoms. The entire electromagnetic spectrum is much more than just visible light. Waves meeting a boundary between mediums may be reflected, refracted or absorbed - often a mixture of all three. That is why it is called the non-ionizing radiation. Spectrum. It encompasses of range of wavelengths of energy that our human eyes can’t see.
