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 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 is incident on a pair of narrow slits that are a distance of 0.10 mmapart. A series of bright and dark fringes is observed on a screen a distance of 2.0 m away. Thedistance between adjacent bright fringes is 8.0 mm.lightscreensecond-order dark fringeslitszero-order bright fringedistance betweenbright fringes = 8.0 mm2.0 mNOT TO SCALEWhat is the path difference of the light waves from the two slits that meet at the second-orderdark fringe?A 2.0  10 –7 mB 4.0  10 –7 mC 6.0  10 –7 mD 8.0  10 –7 m

3.In a Young's double slit experiment, the path difference, at a certainpoint on the screen. between two interfering waves is 1/8th ofwavelength. The ratio of the intensity at this point to that at the centreof a bright fringe is close to

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 decrease. The fringe spacing will increase.

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.
