Discuss the factors that affect the extent of d... - SS2 Physics Optics - Wave Optics Question

The extent of diffraction observed is influenced by two main factors: the size of the obstacle or aperture and the wavelength of light. When the size of the obstacle or aperture is smaller than the wavelength of light, the diffraction is more pronounced. This is because the edges of the obstacle or aperture cause significant interference and bending of the light waves. As the size of the obstacle or aperture approaches or exceeds the wavelength of light, the diffraction becomes less noticeable.

The wavelength of light also plays a crucial role in determining the extent of diffraction. Shorter wavelengths, such as those of blue or violet light, exhibit less diffraction compared to longer wavelengths, such as those of red or yellow light. This is because the shorter wavelength light waves are less affected by the edges of the obstacle or aperture, resulting in narrower diffraction patterns. Conversely, longer wavelength light waves are more prone to bending and spreading out when encountering obstacles or apertures, leading to broader diffraction patterns.
