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[tex]\theta = n\lambda [/tex]
where,
d = slits distance from eachother or width of the slits
[tex]\lambda [/tex] = wavelength
n = interferance order
Also, we know that in Young's experiment, the fringe intensity is given by:
[tex]I' = 4Icos^{2}\phi [/tex]
where,
[tex]\phi [/tex] = phase difference
Therefore, in absence of phase difference i.e., [tex]\phi = 0 [/tex], the intensity of the next bright fringe will not change and it will remain same.
