Description: Which of the following single-slit diffraction experiments would produce the wider diffraction pattern: 800 -nanometer light passing through a 500 -nanometer-wide slit, or 450 -nanometer light passing through a 400 -nanometerwide slit? Why?

Key Concepts

Diffraction Ratio (Wavelength to Slit Width)

The angular width of the diffraction pattern in a single-slit experiment is largely determined by the ratio of the wavelength to the slit width. A higher wavelength-to-slit width ratio results in a wider diffraction pattern, making this ratio a key parameter in determining the spread of the pattern.

Slit Width

The slit width is the physical size of the opening through which the light travels. A narrower slit causes greater diffraction, which in turn broadens the diffraction pattern, making the central maximum and side fringes more spread out.

Diffraction

Diffraction is the bending and spreading of waves when they encounter an obstacle or opening. It is a fundamental wave phenomenon that causes interference patterns, which are used to study wave properties and system geometries.

Single-Slit Diffraction

Single-slit diffraction occurs when light passes through a narrow aperture, resulting in a characteristic interference pattern with a central maximum and multiple side minima and maxima. The pattern's features depend on both the wavelength of the light and the width of the slit.

Wavelength

Wavelength is the distance between consecutive peaks of a wave. In the context of diffraction, longer wavelengths result in more pronounced spreading of the light, leading to wider diffraction patterns when passing through slits or apertures.
