Sodium light ( =6 10⁻⁷ ~m ) is used to produce interference pattern. The observed fringe width is 0.12 mm . The angle between the two wave trains is

Options

  1. A5 10⁻¹ rad
  2. B5 10⁻³ rad
  3. C1 10⁻² rad
  4. D1 10⁻³ rad

Correct answer

B. 5 10⁻³ rad

Step-by-step solution

W = D ~d Angle between the two wave trains is aligned d D & = W & = 6 10⁻⁷ 0.12 10⁻³ & =5 10⁻³ rad aligned
