Expert Solution
Introduction:
- A prism is triangular transparent equipment that is capable of dispersing light. It has an apex and a base. It causes refraction of light and we get a prism spectrum.
- A diffraction grating is made of a large number of equally spaced parallel slits. . The small spaces on the grating will act as slits that diffract light which creates a number of beams that then interfere to produce the spectrum.
- A prism spectrum is a continuous spectrum while a grating spectrum is a line spectrum.
