What will be the effect on interference fringes if red light is replaced by blue light?

What will be the effect on the interferece fringes,if red light is replaced by blue light?

In Young's double-slit experiment, monochromatic light of wavelength 630 nm illuminates the pair of slits prodcues an interference pattern in which two consecutive bright fringes are separated by 8.1 mm. Another source of monochromatic light produces the interference pattern in which the two consecutive bright fringes are separated by 7.2 mm. Find the wavelength of light for the second source. What is the effect on the interference fringes if the monochromatic source is replaced by a source of white light?

Red light is incident on a converging lens of focal length f . State with reason hoe f will change if red light is replaced by blue light.

Study the interference fringes with white light.

A diffraction pattern is obtained using a beam of red light. Which one among the following will be the outcome if the red light is replaced by blue light ?

In case of diffraction from a singel slit, if red light is replaced by a blue light, what will be the effect on the fringe width?

What is the effect on the interference fringes in Young's double slit experiment when the monochromatic source is replaced by a source of white light?
