The figure provided displays the viewing screen in a double-slit experiment. Noting that fringe C is the central maximum, what will happen to the fringe spacing if the spacing between the slits is decreased? The fringe spacing will remain constant. The fringe spacing will increase. The fringe spacing will decrease.

The figure provided shows the light intensity on a viewing screen behind a single slit of width a that is illuminated with red light. What will happen to the width of the central maximum fringe if blue light is used instead? The width decreases. The width remains the same. The width increases.

A researcher uses a single slit diffraction pattern to evaluate a patient's vision.  Which of the following changes will decrease the spacing of the diffraction pattern?A.Decreasing the width of the slitB.Decreasing the wavelength of the lightC.Increasing the wavelength of the lightD.Increasing the intensity of the lightSubmit

Light of a single frequency passes through two narrow slits and produces an interference patternon a screen some distance away. The interference fringes are very close together.Which change would increase the distance between the fringes?A Increase the brightness of the light source.B Increase the distance between the slits and the screen.C Increase the distance between the two slits.D Increase the frequency of the light used.

A pair of slits are illuminated by a coherent source of red light, and the radiation from the slits then illuminates a screen as shown below. The first maximum formed by constructive interference is seen a distance y from the central maximum C.If the light source is changed to blue light, the position of the first maximum will be:Select one:a.Further from the central maximum.b.Closer to the central maximum.c.The same.d.There will be no fringe pattern unless the slit spacing is also changed.

In a double slit experiment using light of wavelength 600nm and the angular width ofthe fringe formed on a distant screen is 0.1°. Find the spacing between the two slits
