In a double slit experiment

\lambda = 405\,nm,

the slit separation is

20\,\mu m

and slit width is

4\,\mu m\,.

Number of bright fringes within central peak of diffraction envelop is:-

View answer and explanation

Correct option: C

Option C (10) is correct because it is calculated by finding the ratio of the width of the central diffraction peak to the fringe width in the double-slit experiment.
