Effect of diffraction is greatest if waves pass through a gap with width equal to
A)frequency
B)wavelength
C)amplitude
D)wavefront

Question

Quizplus · Accepted Answer

The effect of diffraction is greatest when waves pass through a gap or an opening that is approximately the same size as their wavelength. This is because when the size of the opening is comparable to the wavelength, the wave spreads out more significantly after passing through the gap.
