To determine

The distance of dark fringes for the given glass plates.

Expert Solution & Answer
Check Mark

Answer to Problem 40P

  1.08cm

Explanation of Solution

Given:

Length of glass plates, L=26.5cm

Formula used:

Dark bands will occur when 2t=mλ,m=0,1,2,...

The light rays are perpendicular to the plates, the extra path length equals 2t , where t is the thickness of the air gap at any point.

Calculation:

There will be 24 intervals between the 25 dark lines This is half integer with half interval added (have 24.5 intervals). So, between the 25 dark lines there are 24 intervals.

When anyone adds the half-interval at the wire end, there will be 24.5 intervals.

Now, the separation is

  26.5cm24.5intervals=1.08cm

Conclusion:

The required value is 1.08cm .
