Answer:
The distance of the first bright fringe is given as
The distance of the second dark fringe from the central bright fringe is given as
Explanation:
From the question we are told that
The slit separation distance is
The distance of the slit from the screen is
The wavelength is
For constructive interference to occur the distance between the two slit is mathematically represented as
Where m is the order of the fringe which has a value of 1 for first bright fringe
Substituting values
For destructive interference to occur the distance between the two slit is mathematically represented as
m = 2
so the formula to get the dark fringe is
Now substituting values
Answer:
angular range is ( 0.681 rad , 0.35 rad )
Explanation:
given data
wavelength λ = 380 nm = 380 × m
wavelength λ = 700 nm = 700 × m
to find out
angular range of the first-order
solution
we will apply here slit experiment equation that is
d sinθ = m λ ...........1
here m is 1 for single slit and d is =
so put here value in equation 1 for 380 nm
we get
d sinθ = m λ
sinθ = 1 × 380 ×
θ = 0.35 rad
and for 700 nm
we get
d sinθ = m λ
sinθ = 1 × 700 ×
θ = 0.681 rad
so angular range is ( 0.681 rad , 0.35 rad )
