The phenomenon of diffraction is most pronounced when:
A. Obstacle size is much smaller than wavelength
B. Obstacle size is much larger than wavelength
C. Obstacle size is comparable to wavelength
D. Wavelength is zero
Answer: Option C
Solution (By JKSSB Mock Tests)
Diffraction (bending of waves around obstacles) is significant when obstacle or aperture size is comparable to the wavelength of the wave. If size >> λ, diffraction is negligible (ray optics); if size
