Answer:
Explanation:
slit separation d = .17 x 10⁻³ m.
Screen distance D = 5.35 m
angular separation of fringe = λ /d ; λ is wavelength.
Given angular separation in radian
180° = π radian
.19° =
=.0033 radian
.0033 =
λ = .0033 x d
= .0033 x .17 x 10⁻³
= 561 x 10⁻⁹
= 561 nm.
The top of the WINDOW is 19 meters from the ground. also steel balls dont bounce.
