Answer:
Explanation:
distance between two slit d = [tex]\frac{1 \times 10^{-2}}{5510}[/tex]
d = 18.15 x 10⁻⁷ m
Let wave length of light λ
formula for position of first pair of bright spot
Tanθ = λ / d , λ is wave length of light and d is distance between two slit .
Tan 15.4 = [tex]\frac{\lambda}{18.15\times10^{-7}}[/tex]
λ = Tan 15.4 x 18.15 x 10⁻⁷
=5 x 10⁻⁷ m
If θ be the position of next bright spot
Tanθ = 2 λ / d
= [tex]\frac{2 \times\ 5\times\ 10^ {-7}}{18.15\times10^{-7}}[/tex]
=[tex]\frac{2\times5}{18.5}[/tex]
θ = 28.4 degree .
