Question

In a diffraction pattern by a wire,on increasing the diameter of wire,fringe width will
options,:-)
A-increases
B-decreases
C-remains unchanged
D-incresing and decreasing will depend on wavelength​

Answer 1

Answer:

Answer

The fringe width is given as:

β=

d

λ.D

where D= distance of screen from wire, d= diameter of wire

So, when the diameter of wire increases, the fringe width will decrease.
