Consider a bright fringe in a two slit interference pattern. If we look at this point and double the wavelength of the light used in the two slit experiment (such that it still produces a pattern) what happens to this point?Question 4Answera.it remains a bright fringeb.it becomes a dark spotc.it would remain bright or become dark, depending on if the original m value was even or odd. d.it is impossible to tell.

If light illuminates a double slit an interference pattern of alternating bright and dark spots is seen. The intensity of the bright spots is brighter at the centre due to the width of the slits. The bright interference fringes will be readily observed inside the broad central diffraction maximum. Outside this they will be much fainter.A laser of wavelength λ = 650 nm is shone on a pair of slits each of width a = 31 µm. The slit spacing is d = 0.3 mm. The resulting interference pattern is projected on to a screen a distance L= 2.6 m from the double slit.Counting out from the (n= 0) central bright interference fringe, how many more bright interference fringes will be seen before the intensity drops to zero at the edge of the central diffraction maximum.Express your answer to the nearest whole number.

Explain how the interference of light waves creates bright and dark patches in the double-slit experiment.Refer to the model in the previous question to support your answer.

In a two-slit experiment using coherent light, the distance between the slits and the screen is 1.10 m, and the distance between the slits is 0.100 mm. The first-order bright fringe is measured to be 3.40 cm from the centerline. What is the wavelength of the light?

In a two-slit experiment, monochromatic coherent light of wavelength 600 nm passes through a pair of slits separated by 22 micrometers.  At what angle away from the centerline does the first bright fringe occur?

f light illuminates a double slit an interference pattern of alternating bright and dark spots is seen. The intensity of the bright spots is brighter at the centre due to the width of the slits. The bright interference fringes will be readily observed inside the broad central diffraction maximum. Outside this they will be much fainter.A laser of wavelength λ = 650 nm is shone on a pair of slits each of width a = 17 µm. The slit spacing is d = 0.2 mm. The resulting interference pattern is projected on to a screen a distance L= 2.6 m from the double slit.Counting out from the (n= 0) central bright interference fringe, how many more bright interference fringes will be seen before the intensity drops to zero at the edge of the central diffraction maximum.Express your answer to the nearest whole number.
