Question

What is Fringe Width.​

Answer 1

The distance between two successive bright fringe is known as Fringe Width.

Formula :-

$\large{\boxed{\sf \beta=\dfrac{nD\lambda}{d} }}$

• Fringe width is the distance between consecutive dark and bright fringes. It is denoted by 'β'. In case of constructive interference fringe width remains constant throughout. It is also known as linear fringe width.

Answer 2

${\texttt{\huge{\blue{ANSWER !!}}}}$

➡️ Fringe Width

• The distance between any of the consecutive dark and bright fringes are known as Fringe Width.
• It is symbollicaly denoted by the symbol 'β'.
• Also, named as Linear fringe width.

• Formulae : X = λD/d

where :

λ → wavelength

d → distance between slits

X → fringe width

D → distance between slit and screen.
