A spectrum is a band of seven colors obtained after white light is split. This can be understood by the fact that if a white light (sunlight) is passed through a prism and allowed to fall on a white screen, the seven split colors can be seen. The arrangement of the colors are in the order: violet, indigo, blue, green, yellow, orange and red. This arranged group of colors is called a spectrum. A rainbow is an example of a natural spectrum

This also may help you remember the order of the colours in the spectrum-

R(red) O(orange) Y(YELLOW) G.(green) B(blue) I(indigo) V(violet)

you can also remember it as:

(R)ead (O)ur (Y)ellow (G)rafic (B)ecause (I)t's (V)ictorious

What is main difference between prism spectrum and grating spectrum?

Prism spectrum is formed due to DISPERSION but grating spectrum is formed due to DIFFRACTION. In prism spectrum we have only one order but in grating spectrum we can have second order too IN prism spectrum we have continuous spectrum but in gratings we have only line spectrum In prism spectrum red end will be closer to the direct ray but in grating spectrum violet end will be closer to the direct ray

What is Difference between prismatic spectrum and grating spectrum?

Grating spectrum is a spectrum produced as a result of diffraction, as by a grating.Whereas prismatic spectrum is a consequence of dispersion of light by a prism. In grating spectrum you also observe different orders of spectral lines which does not happen in prismatic spectrum. Hope this helps VIBHAV ZUTSHI B.Tech '13 IIT Kharagpur
