Y = +1-3 = -2
X = -5+7 = +2
D = √2^2-2^2 = 2√1+1 = 2√2 km

Explanation:
First we will calculate the energy of single photon using below formula:
Where :
h is plank's constant with value 
c is the speed of light whch is
λ is the wave length = 532nm
E=
J
Number of photons emitted per second:
Number of photons emitted per second=
=
Where:
A-hole is area of hole
A-beam is area of beam
d-hole is diameter of hole
d-beam is diameter if beam
=
=
=
Number of photons travel through pin hole=
Number of photons travel through pin hole=
