beam of electrons is shot through a diffraction grating with 10,000 lines per centimeter. interference pattern on a detector is distance L= 0.3500 m from the thin slits. central maximum width= 1.45 x 10^-6 m. draw a diagram with slits, detector, L, W, and also angular position (theta) of first order minimum in 2 slit interference pattern. find theta, wavelength of electrons in meters, and if you doubled the number of lines per cm, what would happen to the width?

2) White light is being analyzed by a diffraction grating (100 lines/mm). In the interference pattern, the third order blue (wavelength=400 nm) appears 10 cm from the central maxima. How far away is the screen placed from the grating? a) 0.83 m b) 6.52m c) 0.21m d) 8.33m Do you agree or disagree with the statement: "Single-slit interference shouldn't be possible if light was wave; for waves to interfere- you need at least two slits" a) agree b)disagree
