What is the condition regarding the size of the obstacle for observing the diffraction?

Diffraction of light Diffraction of light is the phenomenon of bending of light round corners of an obstacle or aperture and spreading into the geometraicl shadow of the diffracting object. The condition for diffractio of light is the size of the aperature should be comparable to the wavelength of incident light. so in daily life, we find that diffraction of sound is more common than the diffraction of light. width of central maxima is {formula= ((2lambdaD)/d) } In single slit diffraction experiment, if the width of the slit is doubled, if the intensity of central fringe diffraction band becomes.
