When the distance d between the slits is relatively large, there will be numerous bright spots, called fringes. It can be shown that, for small angles (where sin() ≈ , with in radians), the distance between fringes is given by Δy = x/d. Using this result, find the wavelength of light (in nm) that produces fringes 7.50 mm apart on a screen 2.00 m from double slits separated by 0.110 mm

Jackson is designing a new heater, and he wants to experiment with different thermally conductive materials. which of these materials would be useful in conducting heat?

Imagine you work as a consultant, and your daily job involves listening to the constructive criticism of others. as part of your job, you must listen to opposing viewpoints to make important decisions. in this activity, you are a consulting dam engineer. you must make a decision about four different dams; should they be repaired, taken down, or left alone? you will listen to contrasting opinions about what should be done with the dams before you make the final decision. as the consulting dam engineer, what do you decide to do with this dam? explain your reasoning. by making your decision, did you support the opinions of the mayor and/or the dam safety official? why or why not?
