Explain the phenomenon of diffraction of light ... - SS1 Physics Wave Optics Question

Diffraction of light waves refers to the bending of light as it passes through an opening or around an obstacle. It occurs when the size of the opening or obstacle is comparable to or smaller than the wavelength of light. As light waves encounter the edges of the opening or obstacle, they spread out and interfere with each other, creating a pattern of bright and dark regions. The extent of diffraction depends on the wavelength of light and the size of the opening or obstacle. Smaller wavelengths and larger openings or obstacles result in less pronounced diffraction, while larger wavelengths and smaller openings or obstacles lead to more significant diffraction.
