How can the distance between the first bright band and the central band be increased in a double-slit experiment?
Strike441 [17]

Answer:

Decrease the slit separation, increase the distance of the screen from the slits, and increase the wavelength.

Explanation:

The distance y from the central band to the first bright band is given by

y = \dfrac{ \lambda D}{d}

where \lambda is the wavelength of light (or any particle), D is the distance to the screen, and d is the slit separation.

From this equation we see that, by increasing the wavelength \lambda , increasing the distance from the screen D, and decreasing the slit separation d, we increase the distance between the first bright band and the central band.

Therefore, the 2nd choice "<em>Decrease the slit separation, increase the distance of the screen from the slits, and increase the wavelength.</em>" is correct.
