A beam of fast moving alpha particles were directed towards a thin film of gold. The parts 
and 
of the transmitted and reflected beams corresponding to the incident parts 
and 
of the beam are shown in the adjoining diagram. The number of alpha particles in
A
will be minimum and in 
minimum
B
will be minimum and in 
maximum
C
will be minimum and in 
maximum
D
will be maximum and in 
minimum
Text Solution
Verified by ExpertsThe correct answer is:
A
Most of the d-particles will pass through the gold film undeflected and only very small number of 
-particles are reflected by 
. Hence, the number of 
-particles must be maximum in transmitted beam 
and minimum in reflected beam 
.
