Answer:
0.665
Explanation:
use the last formula shown on the lesson manual on acellus and plug it in
The angle of the third dark interference is 0.665.
The wavelength λ = 580 nm
Distance d = 0.000125 m
Line number m = 3
What is the angle of the dark interference?
To find the angle of third dark interference, the formula is,
sin θ = Line number × λ ÷ ( distance)
Substituting all the values,
sin θ = ( 3 × 580 × 10⁻⁹ ) ÷ ( 0.000125)
θ = sin⁻¹ ( 0.0116 )
θ = 0.665
