The phenomenon of diffraction is most pronounced when: MCQ with Answer and Explanation

The phenomenon of diffraction is most pronounced when:
A. Obstacle size is comparable to wavelength
B. Obstacle size is much smaller than wavelength
C. Wavelength is zero
D. Obstacle size is much larger than wavelength
Answer: Option A
Solution (By JKExamLibrary)
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

The dimensional formula of surface tension is
A. [ML⁻¹T⁻²]
B. [ML⁰T⁻²]
C. [MLT⁻²]
D. [MT⁻²]

Correct Answer: Option D


Explanation:
Surface tension = force/length. Force dimensions [MLT⁻²], length [L], so [MLT⁻²]/[L] = [MT⁻²]. Also energy per area gives same dimensions: [ML²T⁻²]/[L²] = [MT⁻²].
