To observe diffraction, the size of the obstacl

Question

To observe diffraction, the size of the obstacle:
A) Has no relation to wavelength
B) Should be λ/2, where λ is the wavelength
C) Should be much larger than the wavelength
D) Should be of the order of wavelength

Askiitians Tutor Team · Accepted Answer

D) Should be of the order of wavelengthTo observe diffraction, the size of the obstacle or aperture should be of the order of the wavelength of the incident wave. Diffraction occurs when a wave encounters an obstacle or aperture that is on the same scale as its wavelength. This means that the size of the obstacle should be comparable to the wavelength for significant diffraction effects to be observed.
