You are working for a craft store in the manufacturing department. The craft store does an excellent businessselling frames for artwork, along with accessories. One of the accessories is nonglare glass. When looking at artwork that is mounted behind normal glass, harsh reflections of the light source illuminating the artwork from the front are reflected into the eye of the observer, often obscuring a view of portions of the artwork. Nonglare glass has a thin film on the outside surface that provides destructive interference for light near the center of the visible spectrum. As a result, there is less reflection to obscure your view. Your department has been selling nonglare glass with the minimum possible thickness to create destructive interference for light of wavelength 590 nm. But the store has been receiving complaints that the very thin film is damaged when the glass is rubbed with a cloth and glass cleaner. As a result, your supervisor asks you to determine the next possible thickness of the film (in nm) that will provide the proper destructive interference. The index of refraction of the glass is 1.65 and the index of rfaci of the film material is 1.42. nm

Need asap ! what is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure? (2 points) as air pressure in an area increases, the density of the gas particles in that area decreases. as air pressure in an area increases, the density of the gas particles in that area increases. as air pressure in an area increases, the density of the gas particles in that area remains constant. as air pressure in an area increases, the density of the gas particles in that area increases and decreases in an alternating pattern. 3. which of the following correctly describes a way in which earth's atmosphere interacts with the geosphere? (2 points) it contains gases that living organisms breathe. it contains gases that trap incoming solar radiation. it provides a medium for cycles that provide nutrients to living organisms. it provides a medium for water to move between earth's surface and the air. 4. which of the following is considered a drawback to using wind energy as a source of power? (2 points) wind energy is nonrenewable. wind energy produces large amounts of air pollution. 5. a meteorologist predicts that the weather in a region will soon change from clear skies to probable thunderstorms. prior to making this prediction, what did the meteorologist most likely observe on a barometer? (2 points) the barometer fell slightly. the barometer fell substantially. the barometer rose slightly. the barometer rose substantially. 6. which of the following do meteorologists not typically use weather balloons to record? (2 points) atmospheric pressure cloud types humidity temperature 7. during which step in the can crush lab did water vapor force air from the can? (2 points) the can was filled nearly to the top with water. the can was placed on the hot stove top burner for several minutes. the can was removed from the hot stove top burner. the can was placed upside-down in the water-filled pan.
