Question

In a single slit diffraction pattern, the distance between the first minimum on the left and the first minimum on the right is 5 mm . The screen on which the diffraction pattern is displayed is at a distance of 80 cm from the slit. The wavelength is 6000 Å .The slit width in ( mm ) is about

Correct answer: C. 0.192

Slit width, (w= D d ) ( aligned & Given, D=80 ~cm =80 10⁻² ~m & =6000 =6000 10⁻¹⁰ ~m & d= 5 2 ~mm = 5 10⁻³ 2 ~m & w= 80 10⁻² 6000 10⁻¹⁰ 2 5 10⁻³ & w=0.192 10⁻³ ~m =0.192 ~mm aligned )
