S_1:Photoelectric effect can be explained on the basis of
particle nature of electromagnetic radiations.
S_2: n = 2, = 1 [IMAGE] 2p-orbital
[IMAGE] dumb-bell shaped.
S_3: d_xy orbital has its lobes directed at an angle of 45º
from X-axis and Y-axis. So, it has zero probability of finding
electrons along X-axis and Y-axis.
S_1:

S_2: n = 2,= 1 [IMAGE] 2p-d{kd
[IMAGE] = (dumb-bell)
S_3: d_xy X- Y- 45º, X- Y
