Question

Monochromatic light passing through a prism doesn't produce:

• A. Spectrum
• B. Diffraction
• C. Refraction
• D. Dispersion

Hint:

Monochromatic light passing through a prism results in dispersion and refraction. Diffraction requires a different setup involving narrow slits or edges.

Answer 1

The Correct Option is B

Monochromatic light passing through a prism will primarily undergo refraction and dispersion. - Refraction occurs when light bends as it enters the prism from one medium to another. - Dispersion occurs because the prism splits the monochromatic light into its constituent wavelengths, creating a spectrum. This is a result of the varying refractive indices for different wavelengths. However, diffraction does not occur in this case because diffraction is a phenomenon that happens when light passes through narrow slits or edges, not through a prism. Thus, the correct answer is diffraction.
