In Example 10.3, what should the width of each slit be to obtain 10 maxima of the double slit pattern within the central maximum of the single slit pattern?

Answer»

SOLUTION :We want `a theta=lambda, theta=(lambda)/(a)`
`10(lambda)/(d)=2(lambda)/(a)a=(d)/(5)=02mm`
Notice that the WAVELENGTH of light and distance of the screen do not ENTER in the calculation of a.
