Solution

The correct option is C $M = 10$

$\frac{O P}{2 D} = \frac{d}{2 D} \Rightarrow O P = d$

$\frac{d}{D} = \frac{O Q}{3 D} \Rightarrow O Q = 3 d$

From both equations:

$Δ y = 2 d = 1 m m$

Also, we know that:
$\frac{y d}{2 D} = (n - \frac{1}{2}) λ$

or $y \geq d \Rightarrow n \geq 5.5, n \leq 15.5$

The correct option is C M=10 OP2D=d2D⇒OP=d dD=OQ3D⇒OQ=3d From both equations: Δy=2d=1 mm Also, we know that: yd2D=(n−12)λ or y≥d⇒n≥5.5,n≤15.5

$\frac{O P}{2 D} = \frac{d}{2 D} \Rightarrow O P = d$

$\frac{d}{D} = \frac{O Q}{3 D} \Rightarrow O Q = 3 d$

From both equations:

$Δ y = 2 d = 1 m m$

Also, we know that:
$\frac{y d}{2 D} = (n - \frac{1}{2}) λ$

or $y \geq d \Rightarrow n \geq 5.5, n \leq 15.5$
