TRUE OR FALSE: In single-slit diffraction, the central band gets thinner as the width of the slit increases.

Respuesta :

Answer:

Explanation:

True

Answer:

TRUE

Explanation:

As we know that position of minimum intensity on the screen at a given angle of the screen is given by equation

[tex]a sin\theta = N\lambda[/tex]

now for width of central maximum we will find the angular width of first minimum

[tex]\beta = \frac{2\lambda}{a}[/tex]

now linear width of the central bright fringe is given as

[tex]w = L \beta[/tex]

[tex]w = \frac{2\lambda L}{a}[/tex]

so we can say that if width of the central fringe will decrease by increasing the width of the slit as they as inversely dependent on each other

So its TRUE
