Light passes through a pair of very thin parallel slits. The resulting interference pattern is viewed far from the slits at vari

butalik [34]

Answer:

Intensity of the next bright fringe will remain same.

Explanation:

The question is based on Young's double slit experiment, since its about bright fringe, the interference here is constructive.

Young's condition for constructive interference is given by:

dsin $\theta = n\lambda$

where,

d = slits distance from eachother or width of the slits

$\lambda$ = wavelength

n = interferance order

Also, we know that in Young's experiment, the fringe intensity is given by:

$I' = 4Icos^{2}\phi$

where,

$\phi$ = phase difference

Therefore, in absence of phase difference i.e., $\phi = 0$ , the intensity of the next bright fringe will not change and it will remain same.

If two teams playing tug-of-war pull on a rope with equal but opposite forces, what is the net external force on the rope?

Rashid [163]

0, Because if they are pulling with equal force then they cancel each other out<span />
