Homework Statement
1. What will happen if we use white light as the source of young's double slit experiment?
2. If the experiment is done in water, what will the effect to the yn? yn is the distance of nth fringe from center fringe.
Homework Equations
d sin θ = nλ
d y/D = nλ
The Attempt at a Solution
1.
I'm not really sure. Will we get some colors of light on the screen like dispersion by prism? If yes, why? Is it because white light consists of several color so each of the color will make different interference pattern because of the difference of wavelength?
2.
The value of yn will decrease because the wavelength will decrease. Am I right?
Thanks
NB : Is there a term for yn? We call the separation of adjacent fringes is fringe separation, so what is the term for the distance of nth fringe from center bright?
