Question

The angular spread of central maximum, in the diffraction pattern, does not depend on ______

• A. the distance between the slit and sources
• B. width of slit
• C. wavelength of light
• D. frequency of light

Answer 1

The correct option is A the distance between the slit and sources

Angular spread of central maxima$=\left(\theta \right)=\frac{\lambda }{b}$

Where $\lambda =$ wavelength of light

$b=$ width of slit

$\Rightarrow$ Clearly, it does depends on the distance between slit and sources.
