To observe diffraction, the size of the obstacle

Ashould be $$\lambda/2$$, where $$\lambda$$ is the wavelength.
Bshould be of the order of wavelength.
Correct Answer
Chas no relation to wavelength.
Dshould be much larger than the wavelength.

Solution

For observing the diffraction of light, the size of the obstacle must be of the order of wavelength due to the wave nature of light. Diffraction can be understood as the bending of waves. So, for greater diffraction, it is important that the size of the particle is directly proportional to the wavelength of the light.
