An application of this principle is that a line mounted on transparent slide casts the same diffraction pattern as a dark film with a slot of equal size cut in it. in part 6.2.5 of the experiment, you will exploit this principle to measure the width of a hair. if the distance between the first spot and the central minimum is s = 0.7 cm, l = 12 m, and λ = 6 x 1 0 ^− 7 , what is the width of the hair (mm)?

Explanation:

It is given that,

The distance between the first spot and the central minimum is, s = 0.007 cm

Length, l = 12 m

Wavelength,

We need to find the width of the hair. Using the condition of diffraction pattern as :

, d is the width of the hair

d = 0.00102

or

So, the width of the hair is . Hence, this is the required solution.

a displacement distance is size of displ
