# Can anyone tell me how to approach and solve this problem?

In a YDSE ,distance between the slits and the screen is 1 m ,separation between the slits is 1 mm and the wavelength of the light is 5000 nm. The distance of 100th maxima from the central maxima is :- $(a)0.5m$ $(b)0.577m$ $(c)0.495m$ (d)Does not Exist

Note :- $1nm=10^{-9}m$

Please post the solution in DETAIL ....

Sort by:

$$\displaystyle y = \frac{n\lambda D}{d}$$

Put n= 100 · 2 years, 9 months ago
