The brightness of fringes increase byincrease of wavelength decreases the brightness.
Reducing the slit separation, a therefore results in the increase in the width of fringes.
making each of the double slits narrower, increases the brightness and the width of fringes is unchanged.
1)Intensity /enrgy/powerrating of the source inciedenting light on double slits increasees
2)Decrease the distance bw the double slit
3)E=1/Lamda so decrease the wavelentgh and Intensity will increase .
4)Increase the WIDTH of both slits without changing the seperation (a) betwenne slits.
