d = 0.221 mm is the spacing (in mm) between the two slits..
here,
wavelength = 589 nm
D = 150 cm = 1.5 m
y = 4 mm
then ,
y = mλD/d
for m = `1
0.004 = 589*10^-9 * 1.5/d
d = 2.21*10^-4 m
d = 0.221 mm
slit spacing is 0.221 mm
The sesmic characteristics of a train depend on the speed of the train, the distance between the wheels, and the hardness of the ground beneath the rails.
Philadelphia attack efficiency aims to improve spacing It continues to lag despite offseason moves, and Harden could have single-handedly fixed these issues.
In a typical hydrogen bond, as atoms move further up the energy ladder, The distance between the energy levels decreases. For Scientists Working at Such Small Scales, these “charging times” are likely candidates for the cause of the distance effect.
