4) A light beam shines through a thin slit and illuminates a distant screen. The central bright fringe on the screen is 1.00 cm wide, as measured between the dark fringes that border it on either side. Which of the following actions would decrease the width of the central bright fringe? (There may be more than one correct choice.) A) increase the wavelength of the light B) decrease the wavelength of the light C) increase the width of the slit D) decrease the width of the slit E) put the apparatus all under water

The actions that would decrease the width of the central bright are decrease in the wavelength of the light and Increase in the width of the slit.

Wavelength of the light

The wavelength of the light is determined using the following formulas;

[tex]\lambda = d(\frac{y}{D} )[/tex]

where;

  • λ is wavelength
  • d is width of the slit
  • D is the distance of the screen
  • y is distance between the central bright fringe and dark fringe

Actions that would decrease the width of the central bright

y = (λD) / (d)

  • Decrease in the wavelength of the light
  • Increase in the width of the slit

Thus, the actions that would decrease the width of the central bright are decrease in the wavelength of the light and Increase in the width of the slit.
