Adouble-slit diffraction pattern is formed on a distant screen. if the separation between the slits decreases, what happens to the distance between interference fringes? assume the angles involved remain small.

the distance between interference fringes increases

Explanation:

For double-slit interference, the distance of the m-order maximum from the centre of the distant screen is

where is the wavelength, D is the distance of the screen, and d the distance between the slits. The distance between two consecutive fringes (m and m+1) will be therefore

and we see that it inversely proportional to the distance between the slits, d. Therefore, when the separation between the slits decreases, the distance between the interference fringes increases.

no

explanation:

no i dont know how to solve this you should probably try to google the answer
