A double-slit interference pattern is created by two narrow slits spaced 0.21 mm apart. The distance between the first and the f
olga nikolaevna [1]

Answer:

\lambda =533.6 nm

Explanation:

the slits spacing, d = 0.21 mm

distance of screen, D = 61 cm

The condition for minima is given as

dsin(\theta) = \left ( n+\frac{1}{2} \right )\lambda

So, first minima, n = 0

dsin(\theta_1) = \frac{1}{2}\lambda

fifth minima, n = 4

dsin(\theta_5) = \frac{9}{2}\lambda

d(sin(\theta_5) -sin(\theta_1))= 4\lambda

For small angle

d(tan(\theta_5) -tan(\theta_1))= 4\lambda

From the figure:

d(\frac{y_5}{D}-\frac{y_1}{D})= 4\lambda

\frac{d}{D} (y_5-y_1) = 4\lambda

\lambda = \frac{d}{4D} (y_5-y_1)

\lambda = \frac{0.021}{4(61)} (6.2 \times 10^{-3})

\lambda =533.6 nm
