No. i can go from my house to New York and back in a day since my final destination is the same as my beginning no work is done. if i go 20 ft from the house and stay i would have done more work. displacement is the key
Answer:
1.28 ×10^-4m
Explanation:
Interference is the superimposition of the wavefront. The superimposition causes bright and dark fringes.
The dark fringe is formed when the additional distance traveled is equal to the multiple wavelength integrals.
From the question, the parameters given are; Wavelength of the light,λ= 600nm, Distance of the screen (D) = 1.44m, order of the bright fringe (m) = 4, Distance of the 4 order fringe (y) = 2.7 cm.
Therefore, for the maximum bright fringe;
dy/D=mλ-----------------------------------------------------------------------------------------------------------------------(1)
Therefore, slotting in equation (1);
d×0.027/1.44=4×600×10^-9
d= 1.28×10^-4 m.
