If red light is replaced by blue light in a single slit diffraction pattern, the fringe width will decrease. This is because blue light has a shorter wavelength compared to red light, resulting in narrower diffraction fringes.

Hii,
When we substitute red light with blue light in a single slit diffraction pattern, the diffraction fringes (bright and dark bands) move closer together. This is because blue light has a shorter wavelength than red light. Shorter wavelengths cause light to bend less, resulting in a smaller pattern.
In summary, using blue light instead of red light brings fringes closer together.
