The width of the diffraction band varies

Question

The width of the diffraction band varies (A) inversely as the wavelength (B) directly as the width of the slit (C) directly as the distance between the slit and the screen (D) inversely as the size of the source from which the slit is illuminated

Tardigrade Admin · Accepted Answer

Width of the diffraction band is given by β =(λ D/d) where D= distance between slit and the screen X= wavelength of light used and d= width of slit. Hence, width of the diffraction band varies directly as the distance between the slit and the screen.

Q. The width of the diffraction band varies

inversely as the wavelength

directly as the width of the slit

directly as the distance between the slit and the screen

inversely as the size of the source from which the slit is illuminated

Width of the diffraction band is given by $β = \frac{λ D}{d}$ where $D =$ distance between slit and the screen $X =$ wavelength of light used and $d =$ width of slit. Hence, width of the diffraction band varies directly as the distance between the slit and the screen.

Width of the diffraction band is given by β=dλD​ where D= distance between slit and the screen X= wavelength of light used and d= width of slit. Hence, width of the diffraction band varies directly as the distance between the slit and the screen.
