Multiplechoice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 2) 10.0 points Two slits are illuminated by a 507 nm light. The angle between the zerothorder bright band at the center of the screen and the fourthorder bright band is 15 . 9 ◦ . If the screen is 133 cm from the doubleslit, how far apart is this bright band from the central peak? Answer in units of cm. 002 (part 2 of 2) 10.0 points What is the distance between the two slits? Answer in units of mm. 003 10.0 points The secondorder bright fringe ( m = 2) is 4 . 63 cm from the center line. 4 . 63cm 1 . 01 m . 0283mm S 1 S 2 θ viewing screen Determine the wavelength of the light. Be sure to use the small angle approximation, sin ( θ ) ≈ θ Answer in units of nm. 004 (part 1 of 3) 10.0 points The viewing screen is a distance 1 . 39 m from a pair of slits with a separation of 0...
