A prism disperses light by refracting it through a prism of a certain material that bends the light at different angles based on its wavelength. On the other hand, a diffraction grating disperses light by diffracting it through a series of closely spaced, parallel lines that create interference when the light passes through it. The interference causes the light to split into its various wavelengths. The prism disperses light more than a grating, which causes the spectral lines to appear brighter.
