1. Violet light falls on two slits separated by 1.90x10^-5 m. A first-order bright band appears 13.2 mm from the central bright band on a screen 0.600 m from the slits. Find the wavelength of the light.

2. Yellow-orange light from a sodium lamp of wavelength 596 nm is aimed at two slits that are separated by 1.90x10^-5 m. What is the distance from the central band to the first-order yellow band if the screen is 0.600 m from the slits?

3. In a double-slit experiment, physics students use a laser with wavelength 632.8 nm. A student places the screen 1.00 m from the slits and finds the first-order bright band is 65.5 mm from the central line. What is the slit separation?

4. Yellow-orange light with a wavelength of 596 nm passes through two slits that are separated by 2.25 x10^-5 m and makes an interference pattern on a screen. If the distance from the central line to the first-order yellow band is 2.0 x10^-2 m, how far is the screen from the slits?
