Question

the fringe space increase by using what light​

Answer 1

Answer:

Increasing the wavelength of the light increases the spacing between different fringes since the spacing between different fringes is wavelength dependent. Red light has the largest wavelength of the color spectrum with a range of 625 - 740 nm, while violet has the smallest wavelength with a range of 380 - 435 nm.
