A slit of width '

a

' is illuminated by light of wavelength

6000 A^0

For What value of 'a will the :- 
(i) First maximum fall at an angle of diffraction of

30^{\circ}

? 
(ii) First minimum fall at an angle of diffraction

30^{\circ}

?

View answer and explanation

Correct option: A

1.8 \mu \mathrm{m}

,

1.2 \mu \mathrm{m}

Option A (

1.8 \mu \mathrm{m}

,

1.2 \mu \mathrm{m}

) is correct because it correctly applies the conditions for the first maximum and first minimum in single-slit diffraction.
