A beam of green light is made to pass through two slits that are 5.0 x 10−3 meters apart. On a screen 4.0 meters away from the slits, an interference pattern appears with bands of light separated by 4.2 x 10−4 meters. What is the wavelength of the light?  a 3.6 x 10−8 m  b 5.9 x 10−7 m  c 5.3 x 10−7 m  d 3.9 x 10−6 m

A beam of yellow light is made to pass through two slits that are 3.0 x 10−3 meters apart. On a screen 2.0 meters away from the slits, an interference pattern appears with bands of light separated by 3.9 x 10−4 meters. What is the wavelength of the light?  3.6 x 10−8 m 5.9 x 10−7 m 6.5 x 10−7 m 3.9 x 10−6 m

A sheet of glass (n = 1.50) is coated with a 500-nm-thick layer of oil (n = 1.39). Using the table provided what is the color of transmitted light?

An optical engineer needs to ensure that the bright fringes from a double-slit are 15.7 mm apart on a detector/ screen that is 1.20 m from the slits. If the slits are illuminated with 633 nm light, how far apart should the slits be? 48.4 μm 74.0 μm 49.5 μm 36.0 μm 8.28 nm   A horizontally polarized beam of light of intensity 100 W/m2 passes through a polarizer with its transmission axis at 40.0° with the vertical. What is the transmitted intensity of this beam of light? 0 W/m2 50 W/m2 64.3 W/m2 58.7 W/m2 41.3 W/m2 Correct answers are underlined can you help explain?
