A lab technician uses laser light with a wavelength of 670 nm to test a diffraction grating. When the grating is 40.2 cm from the screen, the first-order maxima appear 6.02 cm from the center of the pattern. How many lines per millimeter does this grating have?

Light from an argon laser strikes a diffraction grating that has 4,949 grooves per centimeter. The central and first-order principal maxima are separated by 0.488 m on a wall 1.8 m from the grating. Determine the wavelength of the laser light.

Two diffraction gratings, A and B, are located at the same distance from the observation screens. Light with the same wavelength ? is used for each. The separation between adjacent principal maxima for grating A is 2.7 cm, and for grating B it is 3.2 cm. Grating A has 1953 lines per meter. How many lines per meter does grating B have? (Hint: The diffraction angles are small enough that the approximation sin(?) ~ tan(?) can be used.)

Diffraction Grating 2. The same grating is used to measure a laserwavelength. The first-order diffraction spots (maxima) occur atplus-minus 39.49 degrees. What is the laser wavelength? Can we seethis light with our eyes? At this wavelength, how many orders willthe grating produce? (Figure on just the positive side; don’tdouble count.)
