Answer
Vernier caliper measure nearest to 0.01 mm.
If the correct reading of the experiment is 9.62 mm.
But you misread it and listed it as 8.62 mm.
This is Clearly the case of mistake in Accuracy.
Because the reading is wrong and answer is not accurate hence it is mistake in accuracy.
To Judge weather the reading is precise or not we should have a range where the result is acceptable but in the question no range is given. So, we cannot comment on precision.
Answer:
Explanation:
a ) If x be the position of n the bright fringe on the screen , following formula holds .
x = n (λD / d) ; λ is wave length , D is screen distance and d is slit separation .
If we increase the value of λ or wave length, x will increase so central fringe along with all the fringes will shift away from the centre .
If we increase the value of D or screen distance , it will also increase x , so fringes along with central fringe will shift away from the center.
b ) Fringes ,whether bright or dark , both shift together , either towards or away from the center .
So to move the dark spots towards the center , we need to do the opposite to what we did in the first case , ie decrease the wavelength or decrease the screen distance .
