I shine a laser through a grating that is has slits 1.0 x 10-6 meters apart. The result hits the wall 3 centimeters from the grating. The first order constructive interference is 2 centimeters from the central maximum. What is the wavelength of the laser? 435nm 325nm 444nm 555nm 1 points QUESTION 3 I have a 400nm laser, and it strikes a grating with 1.0 x 10-6 slit separation. if the wall is 4 centimeters from the grating, how far is the first order from the central maximum, in centimeters. 1 points QUESTION 4 I have a laser going through 2 slits 0.5 millimeters apart. Once it goes through the slit, it hits a screen 3.3 meters away. The first bright fringe is located 3.4 millimeters away from the central maximum. What is the wavelength of the laser? 515 nm 612 nm 450 nm 310 nm
