Final answer:
The diffraction pattern due to an opaque wire and a slit with the same width are different. The opaque wire produces a diffraction pattern with a dark central band and alternating dark and bright bands. The slit produces a diffraction pattern with a central bright band and alternating dark and bright bands.
Step-by-step explanation:
The diffraction pattern due to an opaque wire and the diffraction pattern due to a slit with the same width are different. When light passes through an opaque wire, it causes diffraction, resulting in a shadow on the other side of the wire. The diffraction pattern consists of a dark central band surrounded by alternating dark and bright bands, known as interference fringes. The central band is wider than the bright bands, and the intensity decreases rapidly on either side of the central band. In contrast, when light passes through a slit with the same width, it also produces a diffraction pattern, but it consists of a central bright band surrounded by alternating dark and bright bands. The bright bands are narrower than the central band, and the intensity decreases slowly on either side of the central band.
