Concept explainers

Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.

Question

## Interference Patterns of Monochromatic Light

The following patterns are created by the interference of monochromatic light. The shaded regions are dark bands whereas the clear regions are bright. Which pattern is caused by single-slit interference?

**Pattern Descriptions:**
- **Pattern (A):** Alternating bright and dark bands of roughly uniform width and spacing.
- **Pattern (B):** Similar to (A) with more frequent bright and dark bands but of almost the same width.
- **Pattern (C):** An area with a wide bright central band and several smaller dark bands on each side, gradually decreasing in intensity.
- **Pattern (D):** Concentric circles with alternating dark and bright rings radiating from a central point.

**Diagrams:**
- **(A):** A series of alternating vertical bands (| | |).
- **(B):** More frequent alternating vertical bands with equal spacing and width (| | | |).
- **(C):** A single bright central area with thinner bands around it ( | | |).
- **(D):** Concentric rings showing circular symmetry.

To identify the single-slit interference pattern, observe the characteristics typically associated with it: a bright central maximum with gradually diminishing bright and dark bands on each side.

**Explanation for Educators:**
This exercise helps students identify single-slit interference patterns among various presented patterns. Single-slit interference typically produces one bright central band with diminishing bright and dark bands on either side. This setup contrasts with double-slit and other multi-slit interference patterns, which usually have evenly spaced fringes, or circular patterns caused by other optical phenomena.

The correct identification of a single-slit interference pattern here is **Pattern (C)**, characterized by its distinctive central bright fringe and diminishing side fringes.
