For dark fringe at P  S1p − S2p =Δ=(2n−1)λ/2   
Here n =3 and l = 6000    
So, =15000AA = 1.5 micron

Given data:
- Wavelength of light, λ = 6000 Å
- Third dark fringe on the screen

Calculating Path Difference:
- For dark fringe, path difference between the waves from S1 and S2 should be equal to (2n-1)λ/2, where n is the order of the fringe.
- For third dark fringe, n = 3
- Path difference = (2*3 - 1) * λ / 2 = 5λ / 2

Converting Wavelength to Microns:
- 1 Å = 0.1 nm = 0.1 * 10^(-3) μm
- Therefore, 6000 Å = 6000 * 0.1 * 10^(-3) μm = 0.6 μm

Final Calculation:
- Path difference = 5 * 0.6 μm / 2 = 1.5 μm

Therefore, the path difference S1p - S2p at the point where the third dark fringe is formed on the screen is 1.5 μm, which corresponds to option B.
