CANA 1F91 Lecture Notes - Double-Slit Experiment, Watt, Retina

In a double-slit experiment, the second-order bright fringe is observed at an angle of 0.54°. If the slit separation is 0.12 mm, then what is the wavelength of the light?

In a Young's double-slit experiment, the wavelength of the lightused is 480 nm (in vacuum), and the separation between the slits is3.00 x 10^-6. Determine the angle that locates each ofthe following.

(a) the dark fringe for which m = 0

(b) the bright fringe for which m = 1

(c) the dark fringe for which m = 1

(d) the bright fringe for which m = 2

In a Young's double-slit experiment, the wavelength of the lightused is 555 nm (in vacuum), and the separation between the slits is1.40 10-6 m. Determine the angle that locates each of thefollowing.
