400 to 700nm in the visible spectrum and begins with blue light and ends with the red. Note: The visible spectrum holds all the colours that we can see and or distinguish. Therefore, the correct answer is option B. The absorption spectrum for chlorophyll can also be called the blue-red spectrum. This begins with the 400nm meter region where the light is blue to the 700nm region, where the light is red. The absorption spectrum of chlorophyll is in the visible range from 400 to 700nm. Chlorophyll is the key pigment produced by the chloroplasts within the plant cell which initiates photosynthesis. Chlorophyll is a pigment present within plants. have been built based on the principle of absorption to identify chemical compounds. Several tools such as a spectrophotometer, laser emission, photoacoustic spectroscopy, etc. It is of vital importance in analytical chemistry, where each compound having a distinct absorption spectrum can be identified by subjecting it to light emission. In simpler terms, a compound will only absorb electromagnetic radiation of a particular wavelength as the electrons within that compound can only absorb or get excited by that particular wavelength. Chlorophyll has an absorption spectrum between the range of 400 to 700nm which constitutes the visible electromagnetic spectrum.Ībsorption of light is the ability of the electron within a compound to get excited and move to a higher state. Absorption is guided by the relationship between the frequency and wavelength of light with that of the compound's ability to absorb photons emitted by the light. Hint: The absorption spectrum refers to the wavelength of light which can be absorbed by a given compound.
