A pair of narrow, parallel slits separated by 0.254 mm are illuminated by green light of wavelength 559 nm. An interference patt
UkoKoshka [18]

Answer: 3.76 mm

Explanation: The formulae that defines the position of a nth fringe from the center of a double slit interference experiment is given below as

y =R×mλ/d

Where y = distance between the nth fringe and the center

R = distance between slits and screen = 1.71 m

m = position of fringe = 1

d = distance between slits = 0.254 mm = 0.000254m

λ = wavelength of light = 559 nm = 559×10^-9m

By substituting parameters, we have that

y = 1.71×1×559×10^-9/0.000254

y = 0.00000095589 / 0.000254

y = 0.00376m = 3.76 mm

g How many diffraction maxima are contained in a region of the Fraunhofer single-slit pattern, subtending an angle of 2.12°, for
lbvjy [14]

Answer:

2

Explanation:

We know that in the Fraunhofer single-slit pattern,

maxima is given by

a\text{sin}\theta=\frac{2N+1}{2}\lambda

Given values

θ=2.12°

slit width a= 0.110 mm.

wavelength λ= 582 nm

Now plugging values to calculate N we get

0.110\times10^{-3}\text{sin}2.12=(\frac{2N+1}{2})582\times10^{-9}

Solving the above equation we get

we N= 2.313≅ 2
