To solve this problem it is necessary to apply the concepts related to the concept of superposition and the fringe separation for double slit experiment.
The equation can be written as

Where
= Distance between fringes
x = distance between slits and screen
d = Distance between slits
= Wavelength
Our values are given as
d= 0.08mm
x =3m

In this way replacing in the equation,




Therefore the distance between the fringes is 2.37cm
PART B) For the case in which it is submerged in water it is necessary to apply the relationship of the fringes with the index of refraction therefore



Answer is in the question :)

Answer:
4.351968e+17 seconds
Explanation:
So I googled age of the universe and it says 13.8 billion years.
you'll have to do some conversions:
in one year, there are 365 days. in one day, there are 24 hours. in one hour, there are 3600 seconds.

so you have to add in the current age of the universe to that equation:

arranged so that the proper "units" will read as "x seconds" at the end of the equation.
then you do the math to find x:
13.8 billion x 365 x 24 x 3600 = 4.351968e+17 seconds.
which would be 435,196,800,000,000,000 seconds
Hope this helps :)
