Learning goal: to understand multislit interference and how it leads to the design of diffraction gratings. diffraction gratings are used in modern spectrometers to separate the wavelengths of visible light. the working of a diffraction grating may be understood through multislit interference, which can be understood as an extension of two-slit interference. in this problem, you will follow the progression from two-slit to many-slit interference to arrive at the important equations describing diffraction gratings. a typical diffraction grating consists of a thin, opaque object with a series of very closely spaced slits in it. (there are also reflection gratings, which use a mirror with nonreflecting lines etched into it to provide the same effects.) to see how a diffraction grating can separate different wavelengths within a spectrum, we will first consider a "grating" with only two slits. recall that the angles θ for constructive interference from a pair of slits are given by the equation dsin(θ)=mλ, where d is the separation between the slits, λ is the wavelength of the light, and m is an integer.

1. the materials manager for a billiard ball maker must periodically place orders for resin, one of the raw materials used in producing billiard balls. she knows that manufacturing uses resin at a rate of 50 kilograms each day, and that it costs $.04 per day to carry a kilogram of resin in inventory. she also knows that the order costs for resin are $100 per order, and that the lead time for delivery is four (4) days.2. at what point should resin be reordered? a. 0 kilograms remainingb. 50 kilograms remainingc. 200 kilograms remainingd. 400 kilograms remaininge. 500 kilograms remaining3. if order size was 1,000 kilograms of resin, what would be the length of an order cycle? a. 0.05 daysb. 4 daysc. 16 daysd. 20 dayse. 50 days4. if the order size was 1,000 kilograms of resin, what would be the average inventory level? a. 50 kilogramsb. 200 kilogramsc. 500 kilogramsd. 800 kilogramse. 1,000 kilograms5. if the order size was 1,000 kilograms of resin, what would be the daily total inventory costs, excluding the cost of the resin? a. $5b. $10c. $20d. $25e. $40
