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

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 meant by grating spectrum?

What are the similarities between prismatic and grating spectrum?
They'll both display a range of wavelengths/frequencies on a target, but given that diffraction gratings are more commonly used (at least in wavelength-multiplexed optic fibre systems), I'd be more interested in the differences.
What is grating constant?
Grating constant is the distance between two rulings present on the grating plate.
What splits light into a spectrum for analysis?
A prism, a diffraction grating, a water droplet, etc.
How can you observe the spectrum in the lab?
You can split white light using a prism or a diffraction grating.
Difference between prism spectrum and grating spectrum?
A prism bends light according to change in refractive index, which can be relatively small (typically a few percent from red to blue) and which varies in different ways for different materials. The prism material may also absorb some wavelengths. A grating bends light according to strict geometry, fairly independent of the material, and the bending is larger. From blue (say, 480nm) to red (around 640) you can get a 15 degree separation with a typical grating. The larger dispersion and the perfectly geometrical calculation of the turn (based on grating spacing and wavelength and initial angle) independent of material make gratings a superior solution for measurement devices.
What is a piece of glass with many small parallel lines etched on its surface to produce a spectrum?
Grating.
What simple device uses diffraction to produce a better spectrum than a prism can be produced?
A diffraction grating does.

What r d differences between spectrometer and spectrograph?
spectrometer is a device that gives the spectrum of all intensities of a one wavelength at one time. it consists of the entrance & exit slits, dispersing element (like grating) &mirror. it detects the light and measure the intensities with a photomultiplier tube or other detectors and data acquisition system. spectrograph also gives the spectrum of all intensities of a wavelength at one time.it consists of the entrance & exit slits, dispersing element (like grating) &mirror but it does not have any detector and does not record the spectrum.
What is grating element?
A.AThe distance between two adjacent slits is known as granting element/Its value is obtained by dividing the length of grating by the by total number of lines ruled on the gratingd=L / NL=length of the grating,N=number of lines ruled on the graring'
