Question

A double-slit interference pattern is produced on a screen using monochromatic light of wavelength 600 nm. What will happen to the separation of the interference fringes (Ay) if you put a tank of kerosene between the double slits and the screen?

Explanation / Answer

2.

y will decrease.

Because while going through the kerosene tank wavelength of the light decreases.

By Snell’s law,

2/1=n1/n2

2=1*(n1/n2)

Thus wavelength in kerosene increases.

Now in double slit interference

dsin=m

d*(y/D)=m

Thus keeping d=slit separation, D= distance from slits to screen we can say that y is derectly depend on wavelength

Thus as increases y increases.
