Given:
The wavelength of the light used, λ=750 nm
The width of the slit, w=0.08 mm=0.08×10⁻³ m
The distance between the slit and teh screen, L=75 cm=0.75 m
To find:
The distance between the central bright band and the first dark band.
Step-by-step explanation:
The distance between the central bright band and the first dark band is given by the formula,
On substituting the known values,
Final answer:
The distance between the central bright band and the first dark band is 7.03 mm
