The word "spectrum" was coined by Isaac newton in the 17th century to describe the band of colors that make up white light when passed through a prism.
The word "spectrum" refers to a wide range of different elements, such as colors or opinions. For example, "The colors of the rainbow form a spectrum in the sky," or "There is a spectrum of opinions on the issue of climate change."
The term "infrared" comes from Latin roots: "infra" meaning below and "red" referring to the color red, which has the longest wavelength in the visible light spectrum. Infrared radiation has longer wavelengths than visible light, hence the name.
Spectra is the plural of spectrum. You could discuss the spectrum generated by an element in a star, and comparing more than one element, you would be comparing spectra. (Latin -um words form plurals like this, so you cannot refer to them as spectrums. Another example is datum, singular, and data, plural.)
The rainbow displayed a beautiful spectrum of colors.
White light, which can split in to the colours is part of the electromagnetic spectrum. Other parts of the electromagnetic spectrum are, cosmic rays, X-rays, UV light, infra red(IR) waves, micro waves, and radio waves. m ic ray of the spectrum
