Answer:
diamerer of the hair (t) 3.11 X 10^{-5} m
Step-by-step explanation:
The first dark spot is at the zero location where the glass plates touch. To find the number of dark fringes after first dark fringe, divide 12 cm by 0.75 mm (.075 cm)
12/.075 = 160.0
total number of additional bright fringe is 156 because there is no further portion for extra dark fringe.
diamerer of the hair (t) can be derived as
2nt = (m + .5)*wavelength
2(1.52)(t) = (160.5)(589.3 X 10^{-9})
t = 3.11 X 10^{-5} m
1 3/5- you flip the second fraction then multiply straight across
hope it helps
