A beam of fast moving alpha particles were directed towards a thin film of gold. The parts $A',\;B'$ and $C'$of the transmitted and reflected beams corresponding to the incident parts $A, B$ and $C$ of the beam, are shown in the adjoining diagram. The number of alpha particles in
$B'$ will be minimum and in $C'$ maximum
$A'$ will be maximum and in $B'$ minimum
$A'$ will be minimum and in $B'$ maximum
$C'$ will be minimum and in $B'$ maximum
