A. If you have completely polarized light of intensity 196 W/m², what will its intensity be after passing through a polarizing filter with its axis at an 65.1º angle to the light’s polarization direction?

B. Find the largest wavelength in nanometers of light falling on double slits separated by 1.77 μm for which there is a second-order maximum.

C. The headlights of a car are 1 m apart. What is the maximum distance in kilometers at which the eye can resolve these two headlights? Take the pupil diameter to be 0.43 cm. Use light of wavelength 514 nm to calculate the answer.

D. Suppose you have a lens system that is to be used primarily for 695 nm red light. What is the second thinnest coating (in nanometers) of fluorite (magnesium fluoride) that would be non-reflective for this wavelength? Assume that fluorite has an index of refraction of 1.38.

E. What is the minimum width of a single slit (in microns) that will produce a first minimum for a wavelength 549 nm?

F. Find the wavelength of light in nanometers that has its third minimum at an angle of 2.74º when it falls on a single slit of width 54.8 μm .

G. How wide, microns, is a single slit that produces its first minimum for 515 nm light at an angle of 21.2º?

Suppose growth in government spending in an economy permanently rises. Using the
AD-AS model, explain the effects of the permanent increase in government
spending growth on the inflation rate and the real growth rate in both the short run and the long
run.
