1. A Young's double slit experiment is performed using light that has a wavelength of 5.3 x 102 nm. The separation between the slits is 3.8 105 m. Find the angles, with respect to the perpendicular bisector of the slits, that locate the first-, second- and third-order bright fringes on the screen.

2. A monochromatic light source is shone on a double slit apparatus, and the interference pattern is projected on a screen 5.3 m away. The slits are 0.21 mm apart. The dark fringes on the screen are 3.8 mm apart. What is the wavelength of the light source?

3.In a double slit experiment, the slits are 0.53 mm apart. The width of the central maximum is 16.0 mm, and the distance between dark fringes is 2.75 mm. What is the width of each slit?
