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. If the first-order bright fringe is measured to be 3.40 cm from the centerline, what is the wavelength of the light?

Wavelength of the light = 3.09 meter

Explanation:

Given:

Distance between slits and the screen = 1.1 meter

Distance between slits = 0.1 mm

First-order bright fringe = 3.40 cm from centerline

Find:

Wavelength of the light

Computation:

Distance between slits = 0.1 mm

Distance between slits = 0.0001 meter

First-order bright fringe = 3.40 cm from centerline = 0.034 meter

Wavelength of the light = [(Distance between slits)(First-order bright fringe)]/Distance between slits and the screen

Wavelength of the light = [(0.0001)(0.034)] / 1.1

Wavelength of the light = [(0.0001)(0.034)] / 1.1

Wavelength of the light = 3.09 meter
