Question

Name the region beyond the violet end, of the spectrum
(A) Infra Violet
(B) Ultraviolet
(C) Dark violet
(D) Light violet

Answer 1

Hint : The spectrum consists of all the various wavelengths of electromagnetic waves, as well as lightweight, radio waves, and X-rays. Ultraviolet light has shorter wavelengths than radio lightweight and Infra-red lightweight has longer wavelengths than gamma light. The sole region within the entire spectrum that our eyes are sensitive to is that visible region.

Complete Step By Step Answer:
First, of all we should always perceive concerning all the terms given.
Electromagnetic spectrum, the complete distribution of electromagnetic waves in keeping with frequency or wavelength. Although all magnetic attraction waves travel at the speed of sunshine in an exceedingly vacuum, they are doing this at a good variety of frequencies, wavelengths, and gauge boson energies. The spectrum contains the span of all electromagnetic waves and consists of the many sub ranges, ordinarily cited as parts, like actinic ray or UV.
Hence, the region on the far side the violet finish of the spectrum is Ultraviolet.
So, the correct option is (b).

Note :
On the far side the violet end of the color spectrum is lightweight of shorter wavelengths and better energies. Our eyes cannot find this lightweight either. This space of the spectrum includes ultraviolet, x-rays, and gamma rays.
Ultraviolet light extends from the violet region of the color spectrum, all the way down to concerning ten nm. Following Herschel's discovery of infrared radiation, Johann Ritter discovered ultraviolet illumination in 1801. By observing the consequences of radiation from the sun on chloride, Ritter determined that radiation existed on the far side of the visible violet.
