6-Light of an unknown wavelength is used to illuminate two parallel slits 1.00 mm apart. Adjacent bright spots on the interference pattern produced on a screen 1.50 m away are 0.650 mm apart. What is the wavelength of the light? A) 433 nm B) 541 nm C) 650 nm D) 758 nm E) 866 nm 7-Light with a wavelength of 500 nm passes through a diffraction grating with 1000 lines/mm. If the screen is 2.00 m away, how far is the first order bright line from the central spot on the screen? A) 0.54 m B) 0.78 m C) 1.00 m D) 1.15 m E) 1.32 m
