Question

580 nm light shines on a double slit
with d = 0.000125 m. What is the
angle of the first dark interference
minimum (m = 1)?
(Remember, nano means 10-9.).
(Unit = deg)​

Answers

  1. Answer:

    .133

    Explanation:

    x=sin^(-1)(((1-(1)/(2))(580*10^(-9)))/(.000125)) took me a while to figure it out but I just took the quiz and I promise this answer is correct please mark brainliest

  2. Answer:

    Angular position of the first minimum is 0.27 degree

    Explanation:

    As we know by the formula of single slit diffraction pattern

    a sin\theta = m\lambda

    here we have

    a = d = 0.000125 m

    for m = 1

    \lambda = 580 nm

    now we have

    0.000125 sin\theta = 580 \times 10^{-9}

    sin\theta = 4.64 \times 10^{-3}

    \theta = 0.27 degree
