what is the basic difference between the spectra obtained through prism and grating?
 
Physics news on Phys.org


i want a clear picture...
 


The resolution of a diffraction grating is much higher than a prism.

Conversely the free spectral range of a prism is much higher than a diffraction grating.

Claude.
 


Nice comparison, Claude, for my own knowledge. Thanks.
