= Solution
The <wavelength> is $\lambda=c/f\simeq0.020\ \mathrm m$. The longest <interferometric baseline> measures the finest angular structure and the <shortest-baseline angular scale> describes the coarsest:
$$
\boxed{\theta_{\rm res}\sim\frac\lambda{B_{\max}}=2.0\times10^{-4}\ \mathrm{rad}\simeq41'',\qquad
\theta_{\rm large}\sim\frac\lambda{B_{\min}}=4.0\times10^{-3}\ \mathrm{rad}\simeq14'}.
$$
These are order-of-magnitude scales, not sharp cutoffs. A commonly used maximum-recoverable-scale convention is $0.6\lambda/B_{\min}$, giving about $8.2'$; reconstruction also depends on baseline coverage and source structure. The individual antenna's <primary beam> is a separate field-of-view limit.<ALMA Basics by National Radio Astronomy Observatory>[“Interferometry”, “Field of view”, and “Imaging of extended structures”]{ref}
