Diffraction and polarisation

Multiple choice

Under what specific condition is the diffraction of a wave through a gap most noticeable?

When the gap width ( $a$ ) is much smaller than the frequency ( $f$ ).

When the gap width ( $a$ ) is approximately equal to the wavelength ( $λ\lambda$ ).

When the gap width ( $a$ ) is approximately equal to the frequency ( $f$ ).

When the gap width ( $a$ ) is much greater than the wavelength ( $λ\lambda$ ).
