Question

A. A diffraction grating has 2400 lines per centimeter. At what angle in degrees will the first-order maximum be for 522 nm wavelength light?

B. What is the wavelength of light (in nanometers) falling on double slits separated by 2.34 μm if the third-order maximum is at an angle of 62.5º?

C. At what angle, in degrees, is the second minimum for 555 nm light falling on a single slit of width 2.35 μm ?

D. Find the distance between two slits that produces the first minimum for 404 nm violet light at an angle of 45.3º. Give your answer in microns.

E. At what angle in degrees is the first-order maximum for 448 nm wavelength light falling on double slits separated by 0.0539 mm?

F. Calculate the minimum angular spreading of a flashlight beam that is originally 5.9 cm in diameter with an average wavelength of 672 nm. Give your answer in 10^-5 radians.

G. At what angle in degrees is the third-order maximum for 581 nm wavelength light falling on double slits separated by 0.05 mm?

H. How many lines per centimeter are there on a diffraction grating that gives a first-order maximum for 485 nm light at an angle of 26.1º?
