Question

In Young's double-slit experiment, for dark fringes, the relationship between the distance from the central axis (y), slit separation (d), screen distance (x), wavelength (λ), and order of fringe (n) is given by:
Options
A yd/x = nλ
B yx/d = nλ/2
C yd/x = nλ/2
Correct Answer
D dx/y = nλ/2
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 3 provides the formula: 'Dark fringes: yd/x = nλ/2; n = 1, 3, 5, 7 ... ... ... ...'.

Hint

Compare the formulas for bright and dark fringes in terms of y, d, x, and λ.
